Re: [JAVA3D] Fullscreen Mode - Help needed
You should be using GraphicsEnvironment object to .getDefaultScreenDevice()
where you right, but then you should use this device to
.setFullScreenWindow(frame) where you are right also. I tried exactly the
same thing as you did, so here is my code to show you how did I get the
GraphicsConfiguration object:
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice d = ge.getDefaultScreenDevice();
if(d.isFullScreenSupported())
d.setFullScreenWindow(frame); // frame is my window
frame
GraphicsConfiguration[] gc = d.getConfigurations();
GraphicsConfigTemplate3D gct = new
GraphicsConfigTemplate3D();
GraphicsConfiguration graphics =
gct.getBestConfiguration(gc);
if(gct.isGraphicsConfigSupported(graphics))
System.out.println("Graphics Device Supported");
else{
System.out.println("Graphics Device NOT Supported");
System.exit(1);
}
Canvas3D c3d = new Canvas3D(graphics);
The JavaDoc says that you have to get the GraphicsConfiguration object from
the Template3D. There may be other ways to get it but I just know this way.
Hope it helps.
Andy

[JAVA3D] Tutorial question
Hi Java3D Dev Team:
In Tutorial 2, it shows that TriangleFanArray is having a parameter of
vertexCount which is TriangleFanArray(vertexCount). However, is this
vertexCount or stripCount? Since I created a Fan with 10 points(vertices)
only including the central point, I should have this ".= new
TriangleFanArray(10, TriangleFanArray.COORDINATES, stripCounts);" instead of
"=new TriangleFanArray(17);". However, if I make it 10, it will
have runtime error. What is the problem? Here is my source code:
private BranchGroup createCone(){
BranchGroup root = new BranchGroup();
// CREATE ALL TRIANGLES //
TriangleFanArray tfa;
int s = 8;
int v = s + 1;
int totalV = v + 1;
Point3f coords[] = new Point3f[v+1];
int stripCounts[] = {17};
float r = 0.5f;
float x, y;
double angle = 360 / s;
coords[0] = new Point3f(0.0f, 0.0f, 0.0f);
for(int a = 1, n = 0; a <= s; a++, n++){
x = r * EngMath.cos(n*angle);
y = r * EngMath.sin(n*angle);
coords[a] = new Point3f(x, y, 0.0f);
}
coords[9] = new Point3f(0.0f, 0.0f, 0.0f);
tfa = new TriangleFanArray(10, TriangleFanArray.COORDINATES,
stripCounts);
tfa.setCoordinates(0, coords);
root.addChild(new Shape3D(tfa));
return root;
}
Please help. Thanks.

Re: [JAVA3D] Tutorial question
Thank you very much, here is my new code which works.
private BranchGroup createCone(){
BranchGroup root = new BranchGroup();
// CREATE ALL TRIANGLES //
TriangleFanArray tfa;
int s = 8;
int v = s + 1;
int totalV = v + 1;
Point3f coords[] = new Point3f[v+1];
int stripCounts[] = {10};
float r = 0.5f;
float x, y;
double angle = 360 / s;
coords[0] = new Point3f(0.0f, 0.0f, 0.0f);
for(int a = 1, n = 0; a <= s; a++, n++){
x = r * EngMath.cos(n*angle);
y = r * EngMath.sin(n*angle);
coords[a] = new Point3f(x, y, 0.0f);
}
coords[9] = coords[1];
tfa = new TriangleFanArray(10, TriangleFanArray.COORDINATES,
stripCounts);
tfa.setCoordinates(0, coords);
root.addChild(new Shape3D(tfa));
return root;
}
Oone more question, strip you said is referring to the Fan, not to the
line between two points?
Sincerely,
Andy

[JAVA3D] Sphere question
Hello all, it's me again: Many of you are graphics genius, you use algorithm to generate points and connect them into a sphere. I was trying to use TriangleFanArray for top and bottom part for sphere, TriangleStripArray for body. However, I would like to know the algorithm of generating a sphere because using both Array to generate a whole sphere is kinda annoying. If I can use a loop to create all points and connect them into triangles and fill it with colors/textures. Would anyone tell me please. Thank you very much.

However, I need to set the source of the light and point to some direction. It just lets me create a directional light "shooting" at a point from original. But I don't want the light from original, I want to make it like from the sky. Is it possible? Hope you understand what I am saying. Thanks.

[JAVA3D] TriangleStripArray Question
Hello all, I saw a 100% pure java applet today and it shows lathe objects. It is very impressive and I saw the source code that the writter wrote this applet by using his own methods, he is not using the TriangleStripArray or the built-in API. My question is that is it possible to use TriangleStripArray or FanArray to do that? Because I tried and it didn't work out. The web said that is a Java 3D engine but is it that I have to create bit by bit like him using my own methods to create a 3D object to be called 3D engine? What if I use TriangleStripArray to create object, does my program call an engine as well?

Re: [JAVA3D] Graphics card
Good things about ATI cards are good features that games are not supported yet and will not be supported in a near future. Facts are: 1. Not quite compatible with Intel and AMD platform. Many of you may heard or think that ATI is compatible to Intel platform, it has problems with AMD platform only. I cannot say that you are wrong but at least my friend experienced that ATI with Intel CPU and chipset are not compatible, always crashes even having updated drivers. 2. Prices are almost the same level as GeForce III but I heard that ATI is cheaper. I guranteer that GeForce III would not give you any trouble but I am not sure about the ATI. So why bother to buy a card just little cheaper but it has unknown issues(no matter good or bad). It is not worth it to take the risk unlessit's refundable so u can give it a try. 3. Qualities in ATI cards are all better than GeForce III or lower series. However, for the performance and stabilities, GeForce III are definitely much better than ATI in scale. Unless you are doing editing or some quality intensive work, otherwise, I won't recommend ATI. 4. ATI OpenGL performance is better now but it is still not good enough. If you say to yourself that you never touch OpenGL stuff like games or Java3D OpenGL, then go for ATI may be good for you. 5. Drivers are not fixed as fast as nVidia. But ATI is improving, this is appreciated. 6. If you want something ultra performance, go for ATI 8500 or GFIII Ti500. Otherwise, go for GFIII Ti200 or just GFIII. These are all my own opinion.

Re: [JAVA3D] Graphics card
Hi, he just mentioned that he wants a GFIII or Radeon 8500, which is recommended and thus I gave my opinion to him. I believe that the purpose of buying this type of card is not only about developing Java3D. If he really wants to develop in Java3D only, my opinion applies again, go for GeForce III since nVidia's OpenGL driver is much better than ATI and Java3D's OpenGL API is written much better than Direct3D version, so finally, still go for GF series.

[JAVA3D] Light and Texture
Hi, I just created a virtual universe and a box. I rotated the box a bit so I can view 3 faces of it. I applied the texture and lights but only the texture was working, I didn't see the lights are working. I applied the AmbientLight and PointLight. When I turned off texture, it was working but if I turned it on, only texture was shown. What would the problem be? Any hints would be appreciated, many thanks.

Re: [JAVA3D] Light and Texture
Thank you very much, I got it fixed, it was a stupid mistake, I didn't add the light to the same transformgroup, I added it to root branchgroup instead..so now is fine. I tried your suggestion, and I didn't see any difference without adding the light, if I add the light, it shows the difference...I learned something from you, thanks a lot.

[JAVA3D] Virtual Universe
Hi all,
I am trying to construct a virtual universe instead of simple universe
because I want to learn it. It compiles but when I run it, it automatically
reboots my system, here is part of my program:
public JEngine(String vu){
// Define a frame
Frame frame = new Frame("JEngine 0.1a");
frame.setLayout(new BorderLayout());
frame.setUndecorated(true);
frame.setBackground(Color.BLACK);
// Set FullScreen mode
GraphicsEnvironment ge =
GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice d = ge.getDefaultScreenDevice();
if(d.isFullScreenSupported())
d.setFullScreenWindow(frame);
// Setup Canvas3D, render the scene and add to universe
GraphicsConfiguration[] gc = d.getConfigurations();
GraphicsConfigTemplate3D gct = new
GraphicsConfigTemplate3D();
GraphicsConfiguration graphics =
gct.getBestConfiguration(gc);
Canvas3D c3d = new Canvas3D(graphics);
Button button = new Button("Exit");
button.addActionListener(new ActionEvents());
frame.add(c3d, BorderLayout.CENTER);
frame.add(button, BorderLayout.SOUTH);
BranchGroup bg = createSceneGraph();
bg.compile();
VirtualUniverse u = new VirtualUniverse();
Locale locale = new Locale(u);
BranchGroup bg2 = createView(c3d);
bg2.compile();
locale.addBranchGraph(bg);
locale.addBranchGraph(bg2);
// Show frame
frame.show();
}
Any hints?
Best wishes,
Andy

[JAVA3D] Behavior Performance
Dear everyone: As I posted my code before, if you have seen my code, please do not laugh at it as I am just a beginner. As you can see in the code that I added the MouseRotate behavior into the TG, but I found that even it's in full screen mode, it is choppy as hell which is not usable. Any suggestion for the performance boost so to make it smooth? I was adding the behavior like the demo BackgroundGeometry.java.

However, when I added KeyNavigatorBehavior into it, it doesn't work at all. I would like to know is there a way to implement the KeyEvents for the view object myself?

Re: [JAVA3D] KeyNavigatorBehavior
I just tried using simple universe instead of virtual universe and the KeyNavigatorBehavior is working like the tutorial said. However, when I use Virtual Universe, it doesn't work, my scene graph is like this: BranchGroup=>TransformGroup, KeyNavigatorBehavior=>TransformGroup=>ViewPlaform. If I take out the KeyNavigatorBehavior, and try to do some transformations to TransformGroup above ViewPlatform, it works, but if I add back the KeyNavigatorBehavior, it doesn't do the Key functions, the transformation is still done. What happens? is it because I add to wrong place?

[JAVA3D] Camera

Re: [JAVA3D] Camera
Sorry for not telling specific enough, here is my code:
/**
* BranchGraph for View BranchGroup
*/
private BranchGroup createView(Canvas3D c){
BranchGroup bg = new BranchGroup();
View view = new View();
view.setSceneAntialiasingEnable(false);
ViewPlatform vp = new ViewPlatform();
vp.setViewAttachPolicy(View.NOMINAL_SCREEN);
PhysicalBody body = new PhysicalBody();
PhysicalEnvironment pe = new PhysicalEnvironment();
view.addCanvas3D(c);
view.attachViewPlatform(vp);
view.setPhysicalBody(body);
view.setPhysicalEnvironment(pe);
TransformGroup tg = new TransformGroup();
tg.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
tg.setCapability(TransformGroup.ALLOW_TRANSFORM_READ);
bg.addChild(tg);
tg.addChild(vp);
KeyNavigatorBehavior key = new KeyNavigatorBehavior(tg);
key.setSchedulingBounds(new BoundingSphere());
bg.addChild(key);
return bg;
}
In this method, it creates the scene graph of the View, ViewPlatform,
PhysicalBody, PhysicalEnvironment. I setup a TransformGroup just above the
ViewPlatform below the BranchGroup. Then I attach the TransformGroup to the
KeyNavigatorBehavior like shown above, and set the SchedulingBounds and
addChild to the BranchGroup. This is what I learned from tutorial but it
doesn't work. Then I tried exactly the same thing from tutorial, using
SimpleUniverse, TransformGroup tg =
simpleuniverse.getViewingPlatform().getViewPlatformTransform(); returns the
TransformGroup between the BranchGroup and ViewPlatform. And I don't have
to modify any methods of keyPressed(KeyEvent e).
I also tried extending the KeyNavigatorBehavior class, and implement the
keyPressed() method, add it to the TransfromGroup of the ViewPlatform, but
it still doesn't work.
Hopefully I give enough information, since I really want to use keys(or I
can config some other keys, not necessary using the specified in
KeyNavigatorBehavior class) to navigator in VirtualUniverse. I am not using
SimpleUniverse since I wanna learn more about the ViewPlatform and stuff.
Thank you very much and waiting for your reply.
Sincerely,
Andy

Re: [JAVA3D] Camera
Here is the method for compiling the branchgroup returned from createView()
method and add to locale:
public JEngine(String vu){
Frame frame = new Frame(vu);
frame.setLayout(new BorderLayout());
frame.setUndecorated(true);
frame.setBackground(Color.BLACK);
GraphicsEnvironment ge =
GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice d = ge.getDefaultScreenDevice();
if(d.isFullScreenSupported())
d.setFullScreenWindow(frame);
GraphicsConfiguration[] gc = d.getConfigurations();
GraphicsConfigTemplate3D gct = new
GraphicsConfigTemplate3D();
GraphicsConfiguration graphics =
gct.getBestConfiguration(gc);
if(gct.isGraphicsConfigSupported(graphics))
System.out.println("Graphics Device Supported");
else{
System.out.println("Graphics Device NOT Supported");
System.exit(1);
}
Canvas3D c3d = new Canvas3D(graphics);
Button button = new Button("Exit");
button.addActionListener(new ActionEvents());
frame.add(c3d, BorderLayout.CENTER);
frame.add(button, BorderLayout.SOUTH);
frame.addKeyListener(new KeyEvents());
BranchGroup bg = createBox();
bg.compile();
VirtualUniverse u = new VirtualUniverse();
Locale locale = new Locale(u);
BranchGroup bg2 = createView(c3d);
bg2.compile();
locale.addBranchGraph(bg);
locale.addBranchGraph(bg2);
frame.show();
}
I followed the scene graph structure, compile the BranchGroup returned from
createView() and add to locale, and locale is attached to the Virtual
Universe. I don't know why the KeyNavigatorBehavior doesn't work that way.
Thanks for replying.

[JAVA3D] Texture not correctly
Here is the method which will create a box with 4 faces only and I load the
texture with TextureLoader and use MODULATE as parameter. It works
perfectly if I create a box with the class Box but not this:
private BranchGroup createBox(){
BranchGroup root = new BranchGroup();
Point3f coord[] = new Point3f[16];
coord[0] = new Point3f(-0.4f, 0.4f, 0.0f);
coord[1] = new Point3f(0.4f, 0.4f, 0.0f);
coord[2] = new Point3f(-0.4f, -0.4f, 0.0f);
coord[3] = new Point3f(0.4f, -0.4f, 0.0f);
coord[4] = new Point3f(0.4f, 0.4f, 0.0f);
coord[5] = new Point3f(0.4f, 0.4f, -0.4f);
coord[6] = new Point3f(0.4f, -0.4f, 0.0f);
coord[7] = new Point3f(0.4f, -0.4f, -0.4f);
coord[8] = new Point3f(0.4f, 0.4f, -0.4f);
coord[9] = new Point3f(-0.4f, 0.4f, -0.4f);
coord[10] = new Point3f(0.4f, -0.4f, -0.4f);
coord[11] = new Point3f(-0.4f, -0.4f, -0.4f);
coord[12] = new Point3f(-0.4f, 0.4f, -0.4f);
coord[13] = new Point3f(-0.4f, 0.4f, 0.0f);
coord[14] = new Point3f(-0.4f, -0.4f, -0.4f);
coord[15] = new Point3f(-0.4f, -0.4f, 0.0f);
int stripCount[] = {20};
TriangleStripArray tsa = new TriangleStripArray(20,
TriangleStripArray.COORDINATES | TriangleStripArray.NORMALS |
TriangleStripArray.TEXTURE_COORDINATE_3, stripCount);
tsa.setCoordinates(0, coord);
TransformGroup tg = new TransformGroup();
tg.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
tg.setCapability(TransformGroup.ALLOW_TRANSFORM_READ);
Shape3D shape = new Shape3D(tsa);
tg.addChild(shape);
Appearance appearance = new Appearance();
TextureLoader tl = new TextureLoader(new
String("./Textures/Floor2.jpg"), new String("RGB"), 0, null);
appearance.setTexture(tl.getTexture());
TextureAttributes ta = new TextureAttributes();
ta.setTextureMode(TextureAttributes.MODULATE);
appearance.setTextureAttributes(ta);
PolygonAttributes pa = new PolygonAttributes();
pa.setCullFace(PolygonAttributes.CULL_FRONT);
pa.setPolygonMode(PolygonAttributes.POLYGON_FILL);
appearance.setPolygonAttributes(pa);
shape.setAppearance(appearance);
MouseRotate mr = new MouseRotate(tg);
mr.setSchedulingBounds(new BoundingSphere());
root.addChild(mr);
root.addChild(tg);
return root;
}
I don't know why the texture was loaded into the lines instead of the box I
created, any hints? Thanks to all of you.

Re: [JAVA3D] Camera
I am too shame of my code, so I didn't send all out. I have all things to
work except JUST the camera moving. I got the button listener as well.
Here attached my code which is able to compile without error. So just
change the createxxx() in the JEngine(String su){} method to create
different polygons. But the KeyNavigatorBehavior in createView() method is
not working. I don't understand why you need the other methods like the
constructor..but anyway may be that just matters. I hope you can help me
this for the KeyNavigatorBehavior so I can use keys to navigate instead of
just mouserotate and zooming. Thanks.

o..it works for you? o my god...what's my problem? when I pressed the

it still didn't work
Anyway, you should not say sorry to your attitude, it was my fault to make

Re: [JAVA3D] Camera
IT WORKS NOW GREAT!!! Thanks!!! But another problemI have to use
my mouse to rotate it first, then I can use cursor to move it...is it
because of the wake thing in Behavior class? Do I have to use start()
method in Behavior class?

Re: [JAVA3D] Graphics card
I am not saying ATI card is bad, but the driver is immature.

[JAVA3D] How to move a camera in the virtual universe using keyboard?
Hi, I am currently trying to have a camera, looking at a cube from the
top view, then when I press up/down/left/right, camera will move along
the x-z plane, since I am using virtual universe, I cannot use
viewingplatform, and I don't like behavior class so I would like to use
normal keylistener attach to the transformgroup of the viewplatform to
make any changes. But when I do that, it does not show anything, but if
I move the cube instead, I can see the cube.
The second question I wanna ask is that how do I use lookAt()? There is
a game engine called irrlicht, which has a camera that has properties:
target and location, target is where the camera looks at and location of
the camera, how do I have the same thing in Java3D? Here is my code of
the transformgroup, any hints? Thanks.
// This is in the main
VirtualUniverse universe = new VirtualUniverse();
Locale locale = new Locale(universe);
BranchGroup objRoot = new BranchGroup();
TransformGroup tg = new TransformGroup();
// Modify the camera here
objRoot.addChild(tg);
tg.addChild(ccube);
objRoot.compile();
locale.addBranchGraph(objRoot);
locale.addBranchGraph(camera.createPanCamera());
// Modify the camera here
camera.move(0, 0, -10);
// This is in the camera class
public BranchGroup createPanCamera(){
// Gravity will be attached later by physics engine
/*** Create all necessary objects for a camera ***/
bGroup = new BranchGroup();
tg = new TransformGroup();
tg.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
tg.setCapability(TransformGroup.ALLOW_TRANSFORM_READ);

[JAVA3D] Moving Camera
Hi, thank you for replying. I tried t3d.invert() with the lookAt() function but it still doesn't work. If I move the cube to (0, 0, -5), it shows me the cube, but I tried to move the TranformGroup between the BG and ViewPlatform by using lookAt(new Point3d(0, 0, 0), new Point3d(0, -5, 0), new Vector3f(0, 1, 0)); and then use t3d.invert(); and then tg.setTransform(t3d); but it doesn't show me anything.

[JAVA3D] Java3D and Mouse Listener question
Hi all, I am currently have a program that has a cube, and a camera. I use mouse event listener to check if the mouse moves to the edge of the program, if yes, then it moves the camera. But if I move my mouse to the edge and stop there, it just checks whenever the mouse moves or not, otherwise, it doesn't know if the mouse pointer is on the edge or not. Then is there any class or method that I can use to check mouse pointer location every single second or loop? Thanks.

Re: [JAVA3D] Java3D and Mouse Listener question
Thank you for replying. I need to check the mouse position constantly even it's not moving, for example, if I move my mouse to (25, 50) and stop moving, when the mouseMoved() method detected that it's inside it will keep doing something until this mouse is moving away from this area. Someone suggests me to use a thread to check constantly inside the method, and use the listener to stop it anytime the mouseMoved() method changes the position. Now what I don't wanna use is thread, I am thinking if it is possible for me to do it C/C++ way like this: Loop Check mouse position IF mouse position is in the area, do something ELSE do nothing End Loop Since I am worring about the thread that will make our program unreliable or unstable, therefore I rarely use thread. The main reason is that since I am trying to make a very simple RTS game, so if mouse moving thread is stop responding or a bit slow because of the CPU time or whatever, it will make the game not synchronized. If I use C/C++ way that dose not use fork, check everything in one flow, it gurantees the flow. Thus, do you have any idea that I can check the mouse position like the loop above without using thread? Since I tried having the mouseMoved() method loads another method that has a loop that checks the mouse position every iteration, but the mouseMoved() method cannot stop it even it changes the variable, I believe it's because of the loop takes highest priority. Thank you very much, I appreciate your help. Andy Florin Herinean wrote: I don't understand why do you want to check the mouse position if the mouse is not moving ??? It's obvious that the position is the last one where a mouse move event was fired. If you really need to know the mouse position at every moment, then just use the mouse move listener to store the position of the event in some convenient place. Then from wherever you are, you can get from there the current position. And don't forget to synchronize access to the mouse position.

Re: [JAVA3D] Java3D and Mouse Listener question
Thanks to all your reply, I will change my design to using thread then, cuz it sounds much easier for me to program in threads this way. :) Andy Florin Herinean wrote: Being afraid of threads is pretty stupid. Threads are what makes things to happen smooth and to promptly react regardless of what else the computer is doing. If you're not using threads, then *everything* in your program will happen sequentialy, i.e. you won't be able to do 2 things simultaneous. Besides that, threads are as stable as anything. If you suppose that a thread may cease functioning, the same might apply to the main thread, the one with the loop. In case you didn't know, everything in java is based on threads. A running java program have at the same time, several threads running simultaneous, even if your program does nothing more than HelloWorld ! Now you're concrete example has a very simple solution: Your "do something" code is in a behavior attached to your scene. You register a mouse move listener with your canvas3d. You check in the listener the current position of the mouse, if it's in the desired area, you start the behavior (if not already started), and if it's out of the area you stop the behavior (if it's not already stopped). The behavior can have a wake criterion as elapsed time or elapsed frames, as you like. You're simply not interested in anything else. And your sistem will be much more responsive, since you're not eating cpu cycles siting in a tight loop. That way you won't explicitly create threads, although you're using at least three of them: the awt dispatcher thread to process the mouse events, the behavior thread which will execute the code inside of your behavior and the rendering thread which will render the image. Learn to think in terms of events: you create events, you react to events.

[JAVA3D] Stopping a thread
I have a question of stopping a thread. I studied the API that I know
that the interrupt will stop a thread. But here is my code:
public void mouseMoved(MouseEvent e){
if(e.getX() <= 1 || e.getX() >= boundary.width - 1 ||
e.getY() <= 1 || e.getY() >= boundary.height - 1){
// Update the mouse position in the camera
before starting or checking the thread
camera.setMousePosition(e.getX(), e.getY());
if(cam.isInterrupted()){
camera.setChecking(true);
cam.start();
System.out.println("Camera is start()" +
e.getX() + ":" + e.getY());
}
}else{
camera.setMousePosition(e.getX(), e.getY());
if(!cam.isInterrupted()){
camera.setChecking(false);
try{
cam.interrupt();
}catch(Exception exception){}
System.out.println("Camera is
interrupt()" + e.getX() + ":" + e.getY());
}
}
}
As you can see that if the isInterrupted() returns false in the else
statement, then it will interrupt the thread, which implies that the
thread is alive and still running so it will interrupt the thread,
right? but everytime I have mouseMoved() detected, it checks if the
mouse pointer is in the area or not, if it is, checks if it is
interrupted or not, if it is interrupted or not, if it is interrupted,
which means it should start the thread again; if it is not interrupted,
which means it's running, it will interrupt. But whenever I move my
mouse in the area, it starts the thread, then once I interrupt the
thread, no matter where I move(exception the area I wanna do something
with, which will start the thread), it just goes into the if statement
showing "Camera is interrupted()"
Any hints?
Many thanks,
Andy

[JAVA3D] Blowing up a texture map
Hello all, I have a generated texture map (simply processing my heightfield and assigning colors) that I mapped onto my terrain. However, I get an unwanted effect. Each triangle is texturized individually, so you get a repeating texture along the terrain in strips. Is there a way to make each triangle a specific color from the map?

[JAVA3D] Advantages of picking over consulting the actual geometry
What is the main reason to use picking in terrain following (or collison detection, or whatever) rather than the actual geometry data? Picking seems to involve a lot of work (creating the pick shape, asking the scene graph for the objects, and then comparing each returned object) versus (in the case of terrain following) asking the terrain to interpolate a height for a given set of coordinates. You get the height at a given point instantly, although this does ignore stuff like buildings you may be in - the framework would need to be extended for that. It seems with a class to automatically determine what is below you, and at what height, would be faster than picking. While the picking API may infact do this, the more generalized implementation must cause slow downs somewhere. Any thoughts? ---Outgoing mail is certified Virus Free.Checked by AVG anti-virus system (http://www.grisoft.com).Version: 6.0.449 / Virus Database: 251 - Release Date: 1/27/2003

I think the simplified model would need to be more complicated than a simple 2d array eventually, to handle multi-story buildings and the like.

Yes, calling these from a user interaction as a result of a mouse click is a common use case. However, it is entirely valid that I should e.g. want to pick the object under my view platform every frame or use these routines to do collision detection.

Also, does anyone know how to get Voodoo3 opengl acceleration to work with Java3D - I believe this entails changing the opengl32.dll so that it uses the voodoo card instead of software rendering but I don't know what to replace it with. === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".

[JAVA3D] Getting Voodoo3 OGL drivers to work with Java 3D 1.2 OGL
I expected it to be so, but sadly such is not the case. It seems that Java 3D does not know to use or find the Voodoo 3 OGL drivers (I'm using the v1.00.00 Win2K drivers) and instead defaults to using the opengl32.dll (which is not replaced by the 3dfx drivers). Copying this over with 3dfxogl.dll doesn't work either. There must be some way to point Java 3D to the 3dfx open gl drivers, anyone know how? I tried the Mesa 3dfx drivers but they were barely faster than the software opengl32.dll and so are pretty much useless in this case. The Java 3D 1.1.3 DirectX SDK 6.1 version on the other hand clearly take advantage of the Voodoo Direct3D drivers. It is obvious from the speed of rendering and also the fact that i get a pixel format error if I set my bit depth to 32 (though the proper behaviour here should have been a default to software rendering. However, it would really be nice if we could get the acceleration working in OpenGL and Java 3D 1.2. - Original Message - From: "John Wright" <[EMAIL PROTECTED]> To: "Andy Sy" <[EMAIL PROTECTED]> Sent: Wednesday, June 28, 2000 4:12 AM Subject: Re: [JAVA3D] getting Java 3D 1.2 OpenGL and/or 1.1.3 DirectX to workwith JavaSDK 1.3 > Andy, > > The Voodoo 3 does hardware acceleration for OpenGL (hence Java 3D 1.2) > without any special installation (just make sure you have the latest > drivers). 3dfx also admits they have a bug in their drivers that > corrupts textures.

[JAVA3D] Java 3D 1.2 OpenGL acceleration under Windows
Rats, now that really stumps me... actually I've been wanting to get 'transparent' hardware accelerated OpenGL support ever since. Like when I was coding Delphi apps that use an OpenGL binding. However for the latter case, i had to specifiy the particular DLL to use (opengl32.dll and glu32.dll) and that's why I thought that the problem for Java 3D 1.2 was similar. (The voodoo 3 drivers never replace opengl32.dll and glu32.dll, instead providing a differently named 3dfxogl.dll) However, accdg to your experience this doesn't seem to be the case. Does anyone know if there's a registry key that points to which dll to use for opengl? - Original Message - From: "John Wright" <[EMAIL PROTECTED]> To: "Andy Sy" <[EMAIL PROTECTED]> Sent: Thursday, June 29, 2000 7:24 AM Subject: Re: [JAVA3D] getting Java 3D 1.2 OpenGL and/or 1.1.3 DirectX to workwith JavaSDK 1.3 > Andy, > > Yes, the Voodoo 3 (under Win98) was definitely providing significant > hardware acceleration (it was outperforming a nearly identical machine > with a Matrox G200 which clearly showed a significant performance > difference depending on what version of drivers were used).

[JAVA3D] OpenGL acceleration under Windoze using Voodoo 3
has anyone here (besides John Wright) gotten Java3D 1.2 OpenGL to run accelerated with their Voodoo 3? Even if it isn't the Voodoo 3 - as long as you were able to get Java3D OpenGL (not DirectX though) to run accelerated, a few tips might help, as I think the problem is Java3D not calling the right OpenGL DLLs. === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".

[JAVA3D] Rotating multiple Objects
Hi.. I'm a little confused. I've worked my way gradually through the sun tutorial but am now stuck. What I wish to do is rotate a number of objects around a central local axis (Local the the group of objects that is). I've created the cubes (3 of them) Translated them to the positions I want adding the individual tranform objects to individual transformgroups and then adding the appropriate cube. I then create a group and add a transformgroup(rotation) to it. I've then added the (three) transform groups (containing the individual cubes) to the group. Every thing is fine if I simply miss out the transformgroup(rotation) on the group but if I do the rotation the cubes disappear. I think this is because the object group is being rotated around some global axis (ie maybe the camera). So how do i rotate the cubes around their central axis point instead of the camera axis. Is this the correct way to do this or should I simple move the camera and if so how do i do that. I know this maybe a bit noddy but everyone has to start somewhere (unfortunately for me thats right back at the begining) Thanks in advance Andy Knight Software Engineer Syngenta === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".

[JAVA3D] Rotating Objects about a point
Hi
I've now managed to get a couple of objects grouped correctly,
scaled and rotating in unison (Thanks Fred Klingener for your help..
I did have trouble link Transform groups btu now I know th order in
which to do this all is fine) but how do I rotate this group around
a set axis.
ie. I have something like this
universe
locale
|-BG1
|-TGc
|- view ("camera")
|-TG1
|-TG2
|-Cube1
|-TG3
|-Cube2
If I rotate the group of objects using TG1 then they always rotate around
the global axis (0,0,0). How do I get them to rotate around another piont
somewhere else in the universe (ie 2,0,4 for instance). Is there any easy
way to achieve this or do I need to do any of the following.
1: Move the group to 0,0,0, rotate them and then move them back to
where they were
or
2: Move the camera instead and "fudge" the view so they look like they
are rotating around a different point.
(maybe easier but I don't know how to do this or even if this is possible)
Thanks again for all your help everyone..
At least I'm getting there and can see the light at the end of the tunnel.
Cheers

Re: [JAVA3D] Andy's int to float problem
Hi Josh,
Thanks for your help but.. i would like to put 0.3 into r and when i run it,
it shows me that r must be a double and not a float. When i change the
float r to double r. The rest of my program shows me alot of errors with
the double r. Are there any way that i can set my r to read a decimal value
without affecting the rest of the program.
Thanks
Andy

[JAVA3D] Using a toolbar to control mouse behaviours..
Hi.. Forgve me if this is a simple question but I'm really struggling to even work how I go about this.. What I would like to do is setup a toolbar on my JFrame and have buttons for specifying what the mouse will do when interacting with my 3D scene. eg a button to pick, a button to rotate, zoom etc.. So that the user clicks, say the zoom button, and when the click and drag on the 3D scene the scene zooms. If the click the rotate buton then when they click and drag on the 3D scene then it rotates.. you get the idea. Writing the mouse behavours themselves is not a problem (ie transforms to zoom) but what I'm having great difficulty in is getting the interaction between by toolbar buttons and the mosue behavours. ie. allowing/passing the toolbar button states to the the 3D mouse behaviours. How on earth do I do this ? Could someone please explain how I do this in easy steps/layman terms as I'm fairly new to Java but understand the basic principles (3D stuff is not a problem as I know about object manipulations etc) its just how I go about the linking of toolbar button to mouse behaviour control.

[JAVA3D] Picking Problems
I have created a scene with some rectangular cubes (ie long tall ones) However picking any of these is so inacurate that it's almost a complete waste of time. I'm crrently picking by bounds using.. pickCanvas.setMode(PickTool.BOUNDS); pickCanvas.setShapeLocation(i, j); pickCanvas.setTolerance(0.05f); PickResult pickresult = pickCanvas.pickClosest(); in the listener. but no matter what i do the picking is inprecise. I've tried all of the following : 1: Turned off the setBoundsAutoCompute and tried to setup my own bounds dfor the object. eg. Create the object. Create a bounds object Set the objects bounds to the bounds object Added the object to the transform (used for rotating) etc.. But it's still very, very messy. I've tried with both a bounding sphere and a boundingbox. The bounding sphere seemed to apply some bounding area but was just as inaccurate as before. I tried and tried but couldn't get the bounding box to work. If I setup the boundingBox eg. myBox.setBounds(new BoundingBox( new Point3d(1,1,1), new Point3d(-1,-1,-1))); and then add the Shape3D (myBox) to the transform above it as before then unless I have setBoundsAutoCompute on then everything dissappears. As a last resort I tried picking by geometry but that was even more of a nightmare. I set up all the correct capabilities (or so I thought) but when i run it I get.. Exception occurred during Behavior execution: javax.media.j3d.CapabilityNotSetException: Shape3D: no capability to allow intersect at javax.media.j3d.Shape3D.intersect(Shape3D.java:434) at com.sun.j3d.utils.picking.PickTool.pickGeomAllSorted(PickTool.java:672 ) at com.sun.j3d.utils.picking.PickTool.pickGeomClosest(PickTool.java:736) at com.sun.j3d.utils.picking.PickTool.pickClosest(PickTool.java:512) at KCNG_3DVis.KCNG_3DVisPickBehaviour.updateScene(KCNG_3DVisPickBehaviour.java: 66) at com.sun.j3d.utils.picking.behaviors.PickMouseBehavior.processStimulus(PickMo useBehavior.java:153) at javax.media.j3d.BehaviorScheduler.doWork(BehaviorScheduler.java:167) at javax.media.j3d.J3dThread.run(J3dThread.java:256) even though I don't seem to have an option on a Shape3D to turn this on (ie setCapability(Shape3D.ALLOW_INTERSECT)). This option is available for the Shape3Ds geometry but setting that still produced the same error. So.. What is the answer.. I'm throughly confused and all out of options. All I would like to do is simply pick an object in my scene and return the userdata associated with it. Any comments or suggestions (no matter how simple or longwinded they are) would be welcome because all this pull out of hair is making me bold.

[JAVA3D] performance comparisons?
Are there any available performance comparisons of Java3D versus OpenGL wrappers like Magician or GL4Java? I am interested in seeing the speed of similar performance-intensive tasks using these different APIs. If not, are there performance test programs written for Java3D which maybe can be adapted to these OpenGL wrappers? thx === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".

[JAVA3D] Still can't get picking together...
Hi.. Sorry to go on.. but this is really getting beyond me. I'm trying to setup a pick by geometry on a shape3D but no matter what I do I just can't seem to get it to work. I've messed with picktools, pick canvases and all other forms of pick objects but I really have no idea about how to put them together. I know what to do to create the scene, transforms and shapes etc.. but I really am lost whn it comes to where to set the right capabilities or how and where to setup the pick canvas/tool etc.. to do this I have read the documentation but that doesn't tell me how to put all this together. (I eventually wish to overide the default picking routines but that will come much later). I would be forever grateful if someone could supply me with either a "Java Recipie" or some sample code (eg: just picking a cube (as a shape3d) based on geometry) Alternatively some code or examples using pick bounds specified by a bounding box would also be useful, as I can't get this to work either (Either the whole scene disappears or it's totally inaccurate) Thanks everyone for your help.. (I know it's a lot to ask) Hopefully one day I will get to grips with this.. Thanks from a newbie..

Re: [JAVA3D] Request for information - serializing classes
Andrew, I have recently subscribed to the list as I am hoping to produce an editor for J3D for the final year project of my Visualisation degree. I have been reading with interest the current debate regarding the pluses and minuses of J3D and in particular your comments about the serialization of classes to store scene graphs: >I'm in danger of digressing here, so I'll return to the original point: >serialization is Java's ace-in-the-hole. Serialization of Java3D objects >is easy to implement (we build everything in 3DSMax but once tweaked in >our J3D editor we serialize it out, be it a humble lonely sphere or a >large scene graph). Java3D does not directly support serialization >however so you have to do it through the back door, and by using >placeholder classes instead of extending Java3D classes. This is a big >weakness in my opinion, and one which I hope will be addressed in a >future release. At present (perhaps naively) this is the area of developing the editor which I foresee causing me most difficulty, although this may say more about my knowledge of serializing Java classes than the ease of the rest of the development work. Any insight you can give me into how you have used your placeholder classes, or pointers to places to read up about the topic would be greatly appreciated.

Re: [JAVA3D] At my wits' end
Tim, >>Clue: Viper v770 32M video card I know several people who have had problems with memory leaks in a number of 3D applications using a Viper video card. The problem appears to be connected with Diamond's drivers for the card as they have all solved the problem by downloading the latest drivers for the TNT chip from www.nvidia.com. You'll lose all the controls which the Diamond's drivers provide such as the performance gauge etc but it'll hopefully get your app working without problems.

[JAVA3D] Zooming using a parallel view
I have a view which uses a parallel projection looking into a J3D world. The view can either be oriented to be a left, top, or front view into the world. I want to allow the user to zoom the view in and out - essentially allowing them to see more or less of the world - without changing the actual size of the Canvas3D used by the view. I've tried translating the view platform towards/away from the centre of the scene but this has no affect on the amount of the scene which can be seen - as you'd expect using a parallel projection (I think). I've also experimented with adjusting the view's screen scale using the setScreenScale(double scale) method. Although this does zoom in and out in a sense, it isn't exactly what I'm looking for. I've achieved the effect I am looking for in the perspective view by adjusting the view platform's distance away from the centre of the scene. Any ideas of how to reproduce this effect in a view with a parallel projection would be much appreciated.

Re: [JAVA3D] Zooming using a parallel view

However, as far as I can tell this technique doesn't work with parallel projection.

[JAVA3D] Lighting and Apperance queries
Hi, I've got a couple of quick queries: In the Windows implementation of Java3D that maps to OpenGL are you restricted to only having eight working lights in the scene as you are in OpenGL? If this is the case, what if any, is the limit in the DirectX implementation? Also, I have an app with up to four seperate views into the same scenegraph as in many modelling packages. Is it possible to force some of the views to render in wireframe and some solid regardless of the objects' appearances? I don't think that changing the Appearance of the objects is an option as this would force all four views to appear the same.

[JAVA3D] Customising Canvas3D
Folks, I am trying to write a customised Canvas3D so that no matter what the given appearance of an object drawn in that canvas it will always be rendered in wireframe. I'm displaying multiple views of the object so actually changing the object's appearance directly isn't an option. To do this I'd considered customising Canvas3D to return an extension of GraphicsContext3D, ConstrainedGraphicsContext3D, when its getGraphicsContext3D() method is invoked. The ConstrainedGraphicsContext3D class would then modfiy any appearances passed to its setAppearance methods so that the polygon attributes ensured the object was rendered in wireframe (I'm assuming that the Canvas3D and GraphicsContext3D works in a similar way to the Canvas and Graphics AWT classes). Unfortunately this hasn't proved possible as the GraphicsContext3D class does not have any public constructors (I assume they have package scope). As far as I know the source for the Canvas3D and GraphicsContext3D classes is not available. Without it I'm pretty much stabbing around in the dark trying to guess what the class does at construction. Any ideas how to overcome this problem, or suggestions for a completely different line of attack would be greatly appreciated.

[JAVA3D] Customising Canvas3D - part 2
Folks, Sorry, but i should have read the JavaDoc more carefully - the getGraphicsContext3D() method on Canvas3D is final so my original plan definitely won't work as far as I can tell. I'd still be very greatful for any suggestions of how else it might be achieved. One thought that occurs to me is that it was mentioned on this list that Java3D 1.2 would see a lot of the final methods being made non-final, can anyone tell me if this is the case with the current beta/alpha release and if it involves the methods I am interested in.

I'm using immediate mode rendering to draw my scene. When certain events occur I want to force the Canvas3D displaying the scene to redraw. To do this I'm using a call to repaint().
