[JAVA3D] AWT not found
Hello!
I have written a class that manage to create a 3D image from a BranchGroup
saved to disk.
This works fine if I run it like a standalone Java Application. It also
works fine if i call this class from a JSP-page running from a Orion server.
But when I try to execute the same JSP-page from a Weblogic 8.1.3 server I
get:
AWT not found
To me it then looks like the AWT package is not included in the JVM for
Weblogic. (It looks like WebLogic uses JRockit as JVM.)
But if I then try to just instansiate a java.awt.Button button = new
java.awt.Button("Push"); on this JSP on Weblogic I get no compiler or
runtime errors. (Then I guess AWT must be available)
In the files j3dcore-d3d.dll and j3dcore-ogl.dll there is a output "AWT not
found". I guess this is where it gets out printed.
1) I do not understand how it could work on one server and not on an other
server. So if any one could explain it it would be great.
2) Is it possible to solve? If yes, how do I solve it?
Best Regards
Fredrik

Re: [JAVA3D] Java3D coordinate system
Ok, say I do that. When I do any picking actions, for instance, picking verticies of an object They will still be in the original coordinate system, right?

[JAVA3D] Coordinates help
Hi J3D Studs,I have a simple wireframe cube displayed (extends Shape3D).Using the following, I can programmatically get at the coordinates:Point3d[] coordinates = new Point3d[24];for(int n = 0; n < 24; n++){ coordinates[n] = new Point3d();}IndexedQuadArray geom = (IndexedQuadArray).getGeometry(); geom.getCoordinates(0, coordinates);System.out.println("coordinateFirst = "+coordinates[0].toString());I've allowed this cube to be transformed by the mouse - moved around, scaled, and rotated.No matter what the state of the cube though, they coordinates I get in the above code are the same. I can't for the life of me figure out how to get the real coordinates of this cube. If I've enlarged the cube to be absolutely enormous, I still get the same coords as if it is really small.Please, anyone...how can I get the true coords of this cube?cheers.===

You have to set the objects you want to pick as "pickable". If they
aren't set as pickable they won't trigger a pick.

I have a branchgroup (not the top level group) that has a number of

I pass the branchgroup and the canvas3D object to the following behavior:

private PickRay createPickRay(Canvas3D canvas, int x, int y) {
Point3d eye_pos = new Point3d();

}
It is initialized as such:
Highlight mousemoveBehavior = new Highlight(cv, bgNodes);
mousemoveBehavior.setSchedulingBounds(new BoundingSphere());
bg.addChild(mousemoveBehavior);
Where bgNodes is the aforementioned branchgroup with all the points and bg
is the top-level branchgroup.
However, the Highlight behavior does not seem to detect any geometry. If
I assign the behavior to the top-level branchgroup, it appears to detect
other geometry in the scene (although I have trouble following the
debugger output).
Can anyone help clarify how I should be doing this?

I am new to Java 3D and am having trouble with picking behaviors. The

Vector3d direction = new Vector3d(mouse_pos);
direction.sub(eye_pos);
return new PickRay(eye_pos, direction);
}
}
It is initialized as such:
Highlight mousemoveBehavior = new Highlight(cv, bgNodes);
mousemoveBehavior.setSchedulingBounds(new BoundingSphere());
bg.addChild(mousemoveBehavior);
Where bgNodes is the aforementioned branchgroup with all the points and bg
is the top-level branchgroup.
However, the Highlight behavior does not seem to detect any geometry. If
I assign the behavior to the top-level branchgroup, it appears to detect
other geometry in the scene (although I have trouble following the
debugger output).
Can anyone help clarify how I should be doing this?
Regards,
Todd

[JAVA3D] getGeometry help
Hi J3D Folks, I have a couple of questions I was hoping someone could help me figure out. Firstly, I have a geometry object that extends Shape3D. It is a wireframe rectangle. I'm allowing the user to move it around and enlarge/shrink it. How can I programmatically access the current position and size of the object? Secondly, how can I restrict movement of this object to an area smaller than my canvas3D? Thirdly, the object is moved within a larger wireframe cube. Within that larger cube I have a bunch of points plotted. I would like to programmatically figure out which points are within the smaller wireframe cube at any given time (and change the color of them to visually tell the user that they are within said smaller cube.) Thank you very much for any ideas you may have. Cheers, ./dylan === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".

Re: [JAVA3D] drawAndFlushImage flickering
I am not familiar with drawAndFlushImage but a long time ago I had a similar problem with overlay-drawing in postSwap and had to add the following line after 2D-drawing to avoid flickering: Toolkit.getDefaultToolkit().sync(); You can try that. /Östen Lundahl Hennie Kotze wrote: Greetings I really hope someone can help me with this problem.

Re: [JAVA3D] drawAndFlushImage flickering
Hennie, Ok, you have my heartfelt condolences. I agree that enough people desire to do "overlays" that a reasonable implementation should just come packaged with Java 3D. You might want to try contacting David Yazel (Xith). I'm fairly sure he managed a fairly decent implementation of overlays before he started creating Xith as an alternative to Java 3D. - John Wright Starfire Research Hennie Kotze wrote: Greetings I really hope someone can help me with this problem.

[JAVA3D] Need some help with translate and rotate
I am brand new to working with Java3D, although I'm failry fluent with Java itself. I'm having a bit of trouble figuring out a problem I'm working on. I have a cone and linearray (from 0,0,0 to some random point not along an axis, i.e. 3, 5, 6). I am essentially trying to draw an arrow by positioning the cone at the end of the line array. I can draw the line fine and I can get the cone moved out to the point at the end of the line but I cannot figure out how to set the center axis of the cone to be the same as the vector used for the linearray so that it points in the direction I want it to. Nor can I figure out how to use multiple rotate commands (rotX, rotY, rotZ) to achieve the desired effect either with the cone either. Any suggestions? The only examples I can find use one of the rotX, rotY, or rotZ commands and never in conjunction.

[JAVA3D] IMPORTANT: java3d-interest list is being moved
It's been one year since we launched Java 3D as a community source project on java.net. As most of you know by now, the Java 3D team no longer reads this old java3d-interest@java.sun.com mailing list. In order to reduce the amount of time we spend on list maintenance, and to better serve the needs of the community, we will decommission the java3d-interest@java.sun.com mailing list, effective July 15. We plan to automatically move all subscribers from the old list to the new [EMAIL PROTECTED] mailing list. Regrettably, this may lead to some readers getting duplicate messages, if they are already subscribed to the new list under a different e-mail address. We will respond to your requests to remove any duplicate e-mail addresses, or to unsubscribe you, but we would ask for your patience during the transition. Alternatively, you can unsubscribe from the old java3d-interest@java.sun.com list before the transition to avoid this problem. We invite those who wish to do so, to come over to the new forum / interest list now; instructions to do this are included below. Or you can simply wait until we move the list over en masse. If you do subscribe to the new list before July 15, you may want to unsubscribe from the old list to avoid being subscribed twice when we move the list. Please let us know if you have any questions concerning this. Note that this transition will not affect the java3d-interest archive, which we will leave in place for the foreseeable future. -- Kevin Rushforth [EMAIL PROTECTED] Chien Yang [EMAIL PROTECTED] Sun Microsystems SUBSCRIBING TO THE NEW JAVA 3D DISCUSSION FORUM / MAILING LIST The new Java 3D interest list is available either as a discussion forum (which is what most of the community uses) or as a mailing list.

[JAVA3D] WakeupOnElapsedTime for NavigationJButtons
Hi all, i build a JPanel containing a set of JButtons for each type of movement. Everytime the Button isPressed [using ChangeListener in Combination with a Buttonmodel and a Swing.Timer] a command will be send to the Behavior class for navigation, which uses WakeupOnElapsedTime(50)to set up a new Movement every 50ms. If no Button is pressed a dummy command is send and no Transformation will done.

Yes.
I've had to build a 3D-GUI last year myself as a part of the work for
my universities degree.
Aside from the classical 3D-GUI (three orthogonal views as 2D-
projections), I would like to propose the following solution:
* make the inner cube wireframed also (this enables you to use
"picking" more reliably than with a solid / xparent geometry -
picking problem: corners "hidden" by the cubes faces / determining
what the user wanted to pick from an (Z-)ordered list of intersec-
tions)
If you should want to impose the impression that the inner cube
has visible faces rather than just being a wireframe, use Shape3Ds
with some xparency, additionally.
When you stick with the Cube(), you'll probably have to do some
clever maths for scaling and positioning. A wf geometry(array) is
much more flexible in this aspect.
* put some tiny, solid cubes as "handles" at its corners
* use picking along with colouring / hiliting to identify the chosen
geometry / handle. Especially the hiliting can take a lot of
possible surprises for the user from your GUI. The visual feedback
seems essential to me - especially with the sometimes "interesting"
way, picking works.
* use the prebuilt PickBehaviour-classes to move the corners around.
-> PickMouseRotate and PickMouseTranslate (afair), but keep in mind
that when you rotate the model in 3-space, the axes still stay their
way. The standard mousepicking-classes do not respect the orienta-
tion of the current view. This might lead to some nasty surprises.
* use J3Ds cabapilities of scaling instead of rebuilding your geo-
metry every time. Keep an internal variable that stores your current
scalefactor, since after an operation the new size will be "1.0".
* Keep a "reset view" button at hand - in case the user should feel
lost and / or confused.
Maybe you might want to enable the user to have the inner cube
("focus") rendered solid / xparent on demand to get a better impres-
sion of its current form and extent. A Swing-button might serve you
well. (To mix Swing with J3D, please have a look at the FAQ at
J3d.org, in case you haven't done this yet. In short: globally switch
off Swings lightweightness.)
Pros:
+ easy navigation, very little abstraction for the user.
+ no switching between your rendered scene and the three 2D-pro-
jections / no multiported views.
+ very little (or even none at all) context switching for the user.
He/She should be able to do everything that is needed in one con-
text, before switching over to the rest of the (2D-)GUI (if any).
The switching is tiring and requires many long mouse moves. This
is highly inefficient.
Cons:
- nonstandard; the user thus has to be taught how to use this
interface
last but not least:
* keep in mind that picking sometimes might behave a bit strange and
that it might require some tweaking
* have a look at and keep an eye on the (picking) demos delivered with
the J3D-API / documentation / tutorial. The three dimensional game
might help you very much for a start. It is a slight bit similar to
what you want to do. ("FourByFour")
If you want to spare some work, have the user modify only the facing
sides. Three buttons "<- X ->", "<- Y ->" and "<- Z ->" (nice styled
icons, of course) should do the trick.
+ less work for you, easier geometry modification
- less intuitive GUI, more 3D-/2D-context switching for the user,
"heavier mousing". ;-)
- less flexible
HTH.
Regards,
Andre

[JAVA3D] Help with 3D UI Solution
Hi J3D Folks, I am hoping that somebody on this list might be able to help me with a design/coding problem I am facing. I haven't actually coded at all yet as I am not sure how to go about solving this. Anyway, thanks in advance for some guidance. I've got a wireframe cube in which I am plotting some (x,y,z) data. That works well. What I'd like the user to be able to do is effectively crop the data in the cube in a similar fashion to how it is done in 2D using Photoshop. So, for example, when the user chooses to crop the data, they will be presented with a greyed out, quasi translucent cube inside the wireframe cube and by using the mouse, they can move the cube and resize it. Once they have moved the greyed out cube around and size it to include all the data they desire, they can hit enter or whatever, and my code can take over extracting the data plotted within this grey cube and do stuff with it. So, I know how to make cubes and draw points and display triangles. But I have no idea who to make a cube that the user can enlarge by dragging the corners of it or move around by dragging the middle of it. Any thoughts and/or suggestions?

Re: [JAVA3D] openGL/directX selection via webstart
In can ask your user at application start-up
In your bootstrap class check if you are under Windows, then open pop-up a
JOption Pane asking user to choose D3D or OpenGL renderer.
Then set
System.setProperty("j3d.rend","d3d") for D3D or
System.setProperty("j3d.rend","ogl") for OpenGL
After that you can call SimpleUniverse, Canvas3D etc...

Re: [JAVA3D] Space Shuttle Physics?
Jaakko,
It's not the approach I'd take. I would use basic geometry (sin and cos).
So your velocity combined with a pitch and a yaw heading using basic
geometry formulas gives you the new x,y,z position.
You might want to borrow a 3D graphics book from a nearby library that
might give you some new ideas.

Re: [JAVA3D] Space Shuttle Physics?
Thanks for your advices, here is what i have come up with.
Am i approacing the correct thinking?
public void update(long timer_delta) {

Re: [JAVA3D] Space Shuttle Physics?
As Joerg and I stated, there is no reason to use two TransformGroups. Using separate TransformGroups only wastes memory and performance. Perhaps you aren't understanding what a tranform does. The rotation has nothing to do with the positioning (i.e. rotating it doesn't move it in a different direction it just changes the object's orientation). I think you'll find it easier if you keep the position, speed and orientation in separate variables (don't fetch them from the transform!) and just use basic geometry to calculate the new position and orientation and then apply it using the TransformGroup. - John Wright Starfire Research Jaakko Holopainen wrote: Ill post the code here, so this is what i do every 1/100 second: // get current transform Transform3D transform = new Transform3D(); m_transformGroup.getTransform(transform); // the TransformGroup1 explained in the earlier post // get current facing Transform3D facing = new Transform3D(); m_transformGroupObject.getTransform(facing); // the TransformGroup2 explained in the earlier post // check thrust states if (!m_thrustForward && !m_thrustBack) m_accelerateVector.z = 0.0f; else if (m_thrustForward && m_accelerateVector.z < 0.1f) m_accelerateVector.z += 0.005f; else if (m_thrustBack && m_accelerateVector.z > - 0.05f) m_accelerateVector.z -= 0.001f; // TODO: apply the combined effect of the facing & accelerate vectors to the speed vector // for the moment apply only thrust // THIS IS THE PART WHERE I NEED SOME HELP m_speedVector.z += m_accelerateVector.z; // apply the speedvector to this transform Transform3D movement = new Transform3D(); movement.setTranslation(m_speedVector); transform.mul(movement); // update the new transform m_transformGroup.setTransform(transform); === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".

[JAVA3D] TextureUnitStates for terrain rendering
Hi all! I was playing with different parameters for texturing my terrain over weekend, but with no satisfactory results. My idea is to have base layer (grass), and on top of it replace it with alpha blended different texture (snow, for example). In that way I will have a nice transition from grass to snow texture. Below are texture attribures for each TextureUnitState. No matter what parameters I tried, I can't isolate alpha texture to work only on one layer (snow). Is order of states important? What is best I can get are two textures combined (which is OK), but than alpha texture cuts off them both, not only snow (or grass). How could I achieve that? //grass baseTextAtt = new TextureAttributes(); baseTextAtt.setTextureMode(TextureAttributes.REPLACE); //snow mainTextAtt = new TextureAttributes(); mainTextAtt.setTextureMode(TextureAttributes.COMBINE); mainTextAtt.setCombineRgbMode(TextureAttributes.COMBINE_REPLACE); mainTextAtt.setCombineRgbSource(0, TextureAttributes.COMBINE_TEXTURE_COLOR); mainTextAtt.setCombineRgbFunction(0, TextureAttributes.COMBINE_SRC_COLOR); mainTextAtt.setCombineAlphaMode(TextureAttributes.COMBINE_MODULATE); mainTextAtt.setCombineAlphaSource(0, TextureAttributes.COMBINE_PREVIOUS_TEXTURE_UNIT_STATE); mainTextAtt.setCombineAlphaFunction(0, TextureAttributes.COMBINE_SRC_ALPHA); //alpha mask for snow alphaTexAttr = new TextureAttributes(); alphaTexAttr.setTextureMode(TextureAttributes.COMBINE); alphaTexAttr.setCombineRgbMode(TextureAttributes.COMBINE_REPLACE); alphaTexAttr.setCombineRgbSource(0, TextureAttributes.COMBINE_PREVIOUS_TEXTURE_UNIT_STATE); alphaTexAttr.setCombineRgbFunction(0, TextureAttributes.COMBINE_SRC_COLOR); alphaTexAttr.setCombineAlphaMode(TextureAttributes.COMBINE_REPLACE); alphaTexAttr.setCombineAlphaSource(0, TextureAttributes.COMBINE_TEXTURE_COLOR); alphaTexAttr.setCombineAlphaFunction(0, TextureAttributes.COMBINE_SRC_ALPHA); === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".

Re: [JAVA3D] Memory problem
Saeed, textures consume much memory in Java. You should increase heap size of your application by argument -Xmx128m or -Xmx256m... So: java -Xmx256m YourClass Saeed Ansari <[EMAIL PROTECTED]> Sent by: Discussion list for Java 3D API 09.06.2005 19:13 Please respond to Discussion list for Java 3D API To JAVA3D-INTEREST@JAVA.SUN.COM cc Subject [JAVA3D] Memory problem Hello all, I have loaded about 180 vrml object ( .wrl format ).When I load the textures I get the OutOfMemoryException, but without texture it works well.Each object has a 3KB texture.

[JAVA3D] Offscreen rendering and JPEG encoding
I have a server app that uses Canvas3D in offscreen mode. After receiving a request, the app gets the Canvas3D to render into a BufferedImage, then uses JAI to encode the image to JPEG. I've been getting some odd performance stats out of this app, and have been trying to tune it by choosing different kinds of BufferedImage. As far as I can tell, if I use TYPE_3BYTE_BGR or TYPE_4BYTE_ABGR BufferedImage type for the Java3D offscreen rendering, I get a better performing Java3D render, compared with using something like TYPE_INT_RGB. But the problem seems to be that by using xxxBGR format BufferedImage, then the JPEG encoding becomes slower. According to the JAI folks, "you might want to try a component image with bands ordered as RGB". And, indeed, use of TYPE_INT_RGB does seem to yield better performance for JPEG encoding, but, consequentially, the Java3D rendering seems much slower. Has anyone tried to figure out a "best choice" of BufferedImage type, that works fastest for both the Java3D rendering, and the JPEG encoding? I've been doing my testing using jdk 1.5, jai 1.1.2_01 and Java3D 1.3.2, on Fedora Core 3 Linux intel, Solaris 10 sparc, and Windows XP intel. The results for both WIndows and Solaris seem to be similar, but Linux seems to be different from them, so maybe I have to choose a different combo for Linux? -- Russell === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".

Re: [JAVA3D] Memory problem
Hello ,
I am working with IntellijIDEA, and I increased the heap size to 512MB. So now it works for 180 objects but not for 200 objects!!!
And another question: Is it possible to load a vrml object and then clone this object.I have added below my source where I load objects :
BranchGroup bg=new vrmlLoad("03.wrl");
transformgroup.addChild( bg );
bgRoot.addChild( transforngroup );
This loading repeats for 200 objects.

Re: [JAVA3D] IndexedQuadArray or...
Dylan, Although I haven't worked with line strips myself, that does sound like what you'd want to use for wireframe projects.

[JAVA3D] VRML Material Swapping Question
I would like to make a group blink red for example and I've been trying to find a good solution to this. I.e. right now what I have is a choice node which turns on and off wrapping the group, this blinks the objects in or out of existence but i want them instead to blink red, sort of highlight.
