Re: [osg-users] SetImage problem
Selam Osman, Did you try void osg::Image::setOrigin ( Origin<http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00305.html#3eb3fb7f290c3b5ef6122b76d5fe6c69> *origin* ) [inline]function before convert TopLeft image to BottomLeft? May be you won't need any flipping operation before setImage funtion. And another hint, are you sure your captured image's depth is IPL_DEPTH_8U from OpenCV. You have set GL_UNSIGNED_BYTE to image type but may be your type could be IPL_DEPTH_16U or IPL_DEPTH_32U. Hope this helps. Regards.

Hi All, Thanks for your all replies. Brede, I will look all suggested games ASAP. may be it helps me for a while before we grow our project. Jan, I mean motion information data(pitch, roll, yaw, planetary accelaration, velocity and etc). I need a game which has an interface or partial plugin to interrogate the game's motion informations like Microsoft Flight Simulations. I can interrogate FS by FSUIPC framework then I can send these motion data to my any device(for example motion platform or Separate 3D Models). >>There are plenty of free games, but I am not sure what you are after. Yes you are right, there are too much free games, but any of them supports kind of this interface to get relatime motion data.

Hi All, I need a game which is OpenSource or free and it supports users with Telemetry Data (Motion Data) like http://www.thunderisland.com/index.phpbefore we write our own game with motion data support interface.

Re: [osg-users] FBX plugin and previous OSG releases...
Hi Alessandro, Maybe problem in osg plugin interfere. So you can't see from dependency walker. As you see osg plugins aren,t named with their version like osg61 So they can be used which doen,t belong your exiting osg core version. Most probably plugin inteference is your problem. Delete all plugin's on your system(all plugins which you can reach from your Path Environment Variables) and rebuild with your existing OSG version again. This would solve your problem. Regards.

Hi Alessandro, As I understand there is dll hells. Please be careful to reach different version of osg and osg_plugin. Try to use dependency walker to check your programs using dlls.

Hi Simon, Thanks for your advices, but I need to apply unordered rotation. And I don't want to think about rotation apply order. So I can't use direct invert function, rotation should be incremental order, not direct neutralization. Thanks for your advices again. Regards.

Re: [osg-users] Rotation 2 DOF node with 2 Different Matrix.
Hi Paul, Thanks for your reply. I need only one explanation about that; psudo code Matrix model= identity; Matrix matrix1= identity; matrix1->rotate( 10 degree on LOCAL X axis ) matrix1->rotate( 10 degree on LOCAL Y axis ) matrix1->rotate( -10 degree on LOCAL X axis ) matrix1->rotate( -10 degree on LOCAL Y axis ) model->setMatrix( matrix1 ) matrix1 is NOT IDENTITY at last. // Do you think it is impossible rotating due to 2 different LOCAL axis on same matrix? I have tried your suggestion but can't resolve; psudo code Matrix model= identity; Matrix matrix1= identity; Matrix matrix2= identity; matrix1->rotate( 10 degree on LOCAL X axis ) model->setMatrix(matrix1 * matrix2); // Turned Local X axis 10 degree matrix2->rotate( 10 degree on LOCAL Y axis ) model->setMatrix(matrix1 * matrix2); // Turned Global Y axis 10 degree matrix1->rotate( -10 degree on LOCAL X axis ) model->setMatrix(matrix1 * matrix2); // Turned Local X axis -10 degree matrix2->rotate( -10 degree on LOCAL Y axis ) model->setMatrix(matrix1 * matrix2); // Turned Global Y axis -10 degree model is IDENTITY at last. // As you said I hold different rotation Matrix for each Axis, but as you can see from above code some rotations done on LOCAL and some rotations done on GLOBAL axis. But I want to do all rotations on LOCAL axis without any artifacts. I know below formulation; /// m = rotation * m; // rotate around matrix axis (local space) m = m * rotation; // rotate around fixed axis (global space) /// But if I change " model->setMatrix(matrix1 * matrix2); " formulation for Y Axis to " model->setMatrix(matrix2 * matrix1); ", this time as a result some frame jumping occured on rotation operations. Do you think it is impossible to operate absolute matrix multiplication for 2 different Local axis on one model? If I operate incremental matrix multiplication for 2 different Local axis I can rotate my model pretty easy but this time I might not reach initial rotation state for this model although I rotate reverse direction for each axis but in different order. Am I trying to achieve impossible operation or not? Thanks so much. Regards. Ümit Uzun 30 Aralık 2009 23:48 tarihinde Paul Martz yazdı: > I would store the x and y rotations as separate variables.

[osg-users] Rotation 2 DOF node with 2 Different Matrix.
Hi All, I have a problem about rotating one MatrixTransform node with 2 different Matrix which one of responsible for rotation on X by osg::X_AXIS and one of responsible for rotatin by osg::Y_AXIS. I have done some rotation to MT node but after this operations I am waiting to get Identity matrix for MT which has Identity matrix in initial state. Some psudo codes; - // Initial states osg::MatrixTransform* MT; MT->setMatrix( osg::Matrix::identity() ); osg::Matrix ang1 = osg::Matrix::identity(); osg::Matrix ang2 = osg::Matrix::identity(); // Updates done with this codes ang1.preMult(osg::Matrix::rotate(osg::Quat(osg::DegreesToRadians(10.0f), osg::X_AXIS))); ang2.preMult(osg::Matrix::rotate(osg::Quat(osg::DegreesToRadians(10.0f), osg::Y_AXIS))); MT->setMatrix(ang2 * ang1); - if I rotate my MT by above code; model rotated on Y by localCoordinate axis and rotated on X fixedCoordinate axis. But I wanted to rotate on X local coordınate axis too. If I use one matrix to update rotation; - // Initial states osg::MatrixTransform* MT; MT->setMatrix( osg::Matrix::identity() ); osg::Matrix ang1 = osg::Matrix::identity(); // Updates done with this codes ang1.preMult(osg::Matrix::rotate(osg::Quat(osg::DegreesToRadians(10.0f), osg::X_AXIS))); ang1.preMult(osg::Matrix::rotate(osg::Quat(osg::DegreesToRadians(10.0f), osg::Y_AXIS))); ang1.preMult(osg::Matrix::rotate(osg::Quat(osg::DegreesToRadians(-10.0f), osg::X_AXIS))); ang1.preMult(osg::Matrix::rotate(osg::Quat(osg::DegreesToRadians(-10.0f), osg::Y_AXIS))); MT->setMatrix(ang1); - With above code I can rotate my model X and Y local coordinate axis. But this code has lack too. After apply positive and negative way rotation I am waiting to get IdentityMatrix but after all rotation operation my MT->getMatrix() give me different from IdentityMatrix. I think I should use inverse matrix instead of negative direction rotated matrix to rotate -X or -Y direction. Could it solve my problem or not? By these 2 rotation operations my main goal is that; I want to rotate MT by X and Y local coordinate system. And after all rotations I can get initial state of MT. I mean I apply to many rotation transformation to my unique node and after all dual(for X and -X or for y and -Y with unordered queue) operation I want to get first initial matrix for my MT node. I know this is not hard operations, but I am unstable about choosing which one is right way. I appreciate any comments. Regards.

Re: [osg-users] HUD-Problem
Hi Carl,
Please download
http://www.openscenegraph.org/projects/osg/attachment/wiki/Support/Tutorials/NPS_Tutorials_src.rarand
test Tutorial_06 which is given link osgHud in OSG website by you. I
have already tried and it is working pretty good. I think your problem was
that you didn't control model's path. So you can't see any hud on the
screen. Please control all path's on your system and recompile it. You will
see all of them works.

Re: [osg-users] Simple water effects
Hi Dominic, thanks for the interesting "links", but the habib tuturials are all for direct x, right? And I don't see how I have to integrate with OSG (sorry for the stupid questions, but I'm a beginer at all...). Yes right. But he has good understanding to achieve kind of water surface. You can grasp the understanding and make yourself in GLSL. I can't find the real worldz examples on the net, do you have the source? Grab the GLSL book and look at Real Worldz section. There is not comprehensive source code and example, there is only information to how you can create water surface. If you are very beginner, you need to learn "water mathematic"(which habib's talked about enough in his site) and implementation by GLSL. I think you have already known this is not trivial operation.

Re: [osg-users] Simple water effects
Hi Dominic; As you know there is too much resource on the net. Some of them which I can advice you to look, http://habib.wikidot.com/ OrangeBook (aka GLSL Book) There is Real Worldz chapter which talk about rendering ocean in simple and not comprehensive way. http://www.vterrain.org/Water/ I don't know which way is the best, simple textures, normal mapping or shaders? What I would like to see is the sun reflecting the rays on the water ;-) Any help is welcome. IMHO, you only need Reflection Rays on the water surface with Environment mapping and animated texturing. This 3 combination would give you best ocean surface as you expect without much CPU usage. But I really suggest you to use osgOcean, You can turn on/off much of rendering unit. So you can only use reflection and environment mapping by toggling off all off other which are needs too much processing time. Regards.

Re: [osg-users] GLSL tricks about texturing.
Hi JS, Thanks so much for your detailed explanations. I get your thinking. I have known same think but I didn't sure very well. My last question is, I have declared; uniform sampler2D diffuseTexture; in my fragment shader, although I didn't bind it to osg::Uniform in my main application, I can sample my texture from my shader in Unit 0. Do you think it is weird or not? You have said that; I only need to bind my uniform sampler2d variable in my application to set to related stateset. I didn't set to stateset too, but I get the unit 0 texture value from shader and can see my model textured. Thanks again.

Re: [osg-users] GLSL tricks about texturing.
Hi All, May be my former question not much understandable. I want to try express my problem again. I have a 3D model which is created by Blender. As you guess, model has to many texture on it. After I export my model in standard model type(3ds or what else), I want to make per pixel shading on my model. My question do I have to define all my texture in fragment shader as "uniform sampler2D xxx" and bind this uniform in my related osg::Program one by one to shade my model per pixel lightening? How can I reach related pixel's texture value in fragment shader if I doesn't use sampler2D? For example, now I can access to related pixel's texture value by; uniform sampler2D diffuseTexture; vec4 texture = texture2D(diffuseTexture,gl_TexCoord[0].st); But if I doesn't define my sampler2D to related texture how can I access? Thanks in advance. Regards. Ümit Uzun 2009/10/30 Ümit Uzun > Hi Folks, > > I am using PerPixel lighting on my some model which has created with > Blender. My model has lots of textures on it.

[osg-users] GLSL tricks about texturing.
Hi Folks, I am using PerPixel lighting on my some model which has created with Blender. My model has lots of textures on it. And my question is, do I have to send all textures in uniform variable to shader? That makes all think to complex, doesn't that? I have try to send only one texture to shader and saw that it can texture all of texture on my model instead of only send one. Then I realize that declared "uniform sampler2 sampleTexture" definition doesn't hold the related texture file. It only hold texture unit, I mean 0,1 or 7. My question is what is the standart shadering operation when we have canned model? Should we send texture's to shader or what else? And sending texture is meaningless, because if we have ive or another texture integrated model what should we do this time? We haven't related texture separately? This time what should we send?

Re: [osg-users] [build] How to open OSG in a CView MFC ?
Hi Nemo, I ask DisplaySetting configuration because of some system hardware not support more multisampling and sometimes viewer open up in full screen. Your suspect about stateHandler does not cause this problem. But you should check your m_hWnd. It should be right handler for your CView. Because base parameters to create rendering window boundaries are got from m_hWnd. Regards. Good Luck.

Re: [osg-users] [build] How to open OSG in a CView MFC ?
Ni Nemo, There is osgViewerMFC example in the source, and firstly you should get the rendering way by scratching the codes. And then you can implement your with same way. There is not much example on MFC, so your only chance is osgViewerMFC I think. Regards.

Re: [osg-users] problem in setPivotPoint of PAT for .3DS file
Hi Gopal,
Sometimes canned models pivotpoint set to undesired position which not
suitable your desired pivotpoint position. So to solve this problem you have
two chance, you can open your model by 3D model programs and after you
configure pivotpoint you export it again and use new model or set your
desired pivot position to your PAT node by setPivotPoint. Its usage so
simple. You choose your desired global point to make pivot your PAT node.
For example;
osg::Node* createRoom(osg::Node* loadedModel) // From osgLight example
{
// default scale for this model.
osg::BoundingSphere bs(osg::Vec3(0.0f,0.0f,0.0f),1.0f);
osg::Group* root = new osg::Group;
if (loadedModel)
{
const osg::BoundingSphere& loaded_bs = loadedModel->getBound();
osg::PositionAttitudeTransform* pat = new
osg::PositionAttitudeTransform();
pat->setPivotPoint(loaded_bs.center());
As you can see from attached code we get the models boundingSphere's center
and make it pivotPoint. After this initialization your model will be rotated
around this point by setAttitude command.
You can look at osgLight, osgLauncher and osgLogo too.
HTH.
Regards.

Re: [osg-users] problem in camera rotation
Hi Akilan;
Matrix multiplaction is not commutative. If you change the order of matrix
as a result the accumulated matrix will behave different as you anticipated.
So order of matrix multiplexing is Scale, Rotate and lastly Translate. So in
multiplexting operation order of them as follows;
AccumulatedMatrix = TranslateMatrix * RotateMatrix * ScaleMatrix;
So I suggest you to use one MatrixTransform because you can do all operation
in one MatrixTransform too. And try rotMT->setMatrix(tmatrix * rmatrix); and
delete transMT. Use single MatrixTransform.
HTH.

Hi Filip; This is impossible because all example uses generated library, includes and dll's on your own platform so you have to compile OSG Core library too.

[osg-users] Texturing Operation on osg::Cylinder ShapeDrawable Problem.
Hi All;
If this is much simple question please forgive me :D I am trying to create
wheel body and related texture by using ShapeDrawable and can't. Do I have
to use Modeling tools to create my expected looking images as you can see
from attached image? Or Do I have to manipulate texture coordinate by
programmatically at runtime? What should I do? I can create this wheel easly
by using Blender but I want to create by coding.
ExpectedWheel part had created on DirectX by using same wheel texture.
My Code:
// Wheel
osg::ref_ptr wheelGeode = new osg::Geode();
wheelGeode->addDrawable(new osg::ShapeDrawable(new
osg::Cylinder(osg::Vec3(0.0, 0.0, 0.0), RADIUS, 0.08)));
osg::ref_ptr texWheel = new osg::Texture2D();
texWheel->setImage(osgDB::readImageFile("./Data/wheel.bmp"));
wheelGeode->getOrCreateStateSet()->setTextureAttributeAndModes(0,
texWheel.get(), osg::StateAttribute::ON);
Regards.

Re: [osg-users] Compress image
Hi Ufuk;
If you want to create mippaped images on your disk instead of
programmaticaly. I suggest you to use GIMP to mipmap(rescale each different
resolution image separately) and when you need you can call related
resolution image :)
Is this your expected or you want to create one image which has all
resoluted images in it? If you want kind of this operation you can use dds
format. But I don't know osg does support reading mipmapped dds format.
Regards.

Compress word doesn't define your expected operation very well. This

Re: [osg-users] Reference count catcher?
Hi Ufuk;
As I know, If you create a new object with using ref_ptr, object's default
ref_ptr should be initialized to 1. And after you have attached it to your
scene, ref_ptr count gets 2. And after you delete your geometry from your
scene graph ref count gets 1 again. And then this ref_ptr object will be
deleted automatically when intelligent ref_ptr decided to it is unneccessary
some times later. And then it will be deleted automaticly. Be cool.
ref_ptr's target is counting pointer usage and finding unneccesary pointers.
Regards.

Re: [osg-users] [forum] Help to use osgViewer in MFC
Hi Nguyen; OpenSceneGraph has multithreaded structure on drawing, culling and some kind of operation and singleThreaded structure on update traversal. So if you want to add or remove some nodes from your scene graph you should do this operation any updating operation sector. For example you can create one update callback and you can do these operation in it. Or you have to stop viewer renderer and then you do your add-remove operation and then start threading again. So application doesn't crash. But stopping and starting renderer thread is not best solution. This is my humble opinion. Regards.

You mean it is not working or working but not as expected? I saw a problem
you multiply matrices wrong order. You always obey the TRS rule. First Scale

Hi Paul;

What do you mean about osg::Switch. It's not specific feaute on accumulating
trasformation for osg::Switch as I know. It actual target is switching node
while rendering scene graph.
What type gridOrientation is?
Be careful while multiplying the matricies because precedence is important
for kind of these operations : result = rotation * translation;

Re: [osg-users] what is the thread difference between MFC and console?
Hi Forest; We have same problem and I find that threading isn't actual problem. real one is rendering on specified HWND. And frame rate always gets down while enlarging the HWND size contrary if you collapse the HWND size you can see easily that frame rate gets upper degree than wide one. I suspect that low frame rate is caused by rendering on specified HWND. If you really need to render on MFC control(i.e PictureBox) you should narrow you HWND control size to get high frame rate.

Re: [osg-users] MatrixTransform accumulation
Hi Yang,
Translation operation isn't same as rotation operation. While one object is
rotating in every transformation node by traversing the scene graph from
parent to child, every node can effect the current rotation state to the
target child node.
Distinctly in translation operation every node try to translate target child
node to specified coordinate point which is every PAT node instantiate it
with osg::Vec3(10.0f,10.0f,0.0f). Actually every PAT nodes effect the child
node to locate it osg::Vec3(10.0f,10.0f,0.0f) but only last one is validate
on this operation. Becase PAT4 is the last node before the child node. So
you can't hope to accumulate traslation value as rotation value.
I hope that I did't tell you wrong explanations.

Hi All, Until now, I have been using VS2003 in all project. But we have upgraded to VS2008. I don't know why can't load released OSG in Debug mode or vice versa.

Re: [osg-users] osgOcean 1.0 (LGPL) Released
Hi Kim, I have same problem with samplerRect before when I wanted to try osgMovie example as you suggested to Robert. And I tried to use sampler2d instead of and was solved. And as this problem, osgWidget's Widget class texture operation was only supported with TextureRectange and I have implemented Texture2D to show my movie on it by myself. I think my GPU's main one problem is TextureRectangle implementation. Regards. 2009/6/18 Ümit Uzun > Hi Kim, > > Thanks you so much.

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.
Hi Micheal; Thanks for your polite offer to helping me:) I have looked Bullet and Nvidia PhysX. I can't choose PhysX because I want to run my PhysX engine ATI. I think it's not support. Or do you think it can be modified to send the physics calculation to CPU instead of GPU on PhysX. I had tried to grasp the Bullet but it seems much complicated then ODE, so I choosed ODE. Yes as you said, I have to handle collision detection and create contact with physics dynamics if I choose another collision library instead of own one. So this is big problem, so the real solution seems to use main library of ODE.

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.
Hi Sergey; I have known about Delta3D. It uses ODE too, but I am in contradiction about using pure OSG and ODE or using Delta3D game engine. To use Delta3D I have to spend some to get the structure and wrappers all other library. But with using pure OSG and ODE I can adopt so quickly. Anyway I thanks for your suggestion, and I will try to understand Delta3D's integration way.

[osg-users] Any suggestion about OSG-ODE integration and collision detection.
Hi All, I am planing to create simple off road jeep-racing and I have looked at the libraries to create dynamics and choose ODE. But I can't decide use ODE's collision detection mechanism instead of osgUtil's polytopeintersector, planeintersector or linesegmentintersector classes. So if you were me, which collision detection system would choose? PostScript : I am noob on ODE, this experince will be the first introdution for me. Any suggestion appreciated with glad.

Hi Kim, Firsty congratulations for these awesome works. When I try to create solution file in cmake on VisualStudio2008 I get the errors; CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: FFTSS_INCLUDE_DIR used as include directory in directory C:/Projects/Ocean/osgOcean-Source/src/osgOcean FFTSS_LIBRARY linked by target "osgOcean" in directory C:/Projects/Ocean/osgOcean-Source/src/osgOcean OPENTHREADS_LIBRARY_DEBUG linked by target "osgOcean" in directory C:/Projects/Ocean/osgOcean-Source/src/osgOcean I have compiled the FFTSS library and locate it in same folder with osgOcean-Source folder. Should I declare specific Environment Variable to help cmake for finding right fftss include directory and library? And Do we have to OpenThreads library in debug mode? I have a OSG distiribution in only release mode.

Re: [osg-users] Load PlugIn Library in OsgDB::Registry
Hi Croperli; Look at the http://www.skew-matrix.com/bb/viewtopic.php?f=8&t=3 Troubleshooting the Build Did osgdb_curl.dll fail to link? OSG creates several libraries during a build. One of the libraries, osgdb_curl.dll, has a special dependency on Windows. During the OSG build, if this library fails to link, and the link error indicates that wldap32.lib can’t be found, you’ll need to manually configure Visual Studio’s library search path and possibly install the missing library. Note that the compile works fine, or fails, depending on the compiler you are using. Currently, this is only an issue for some editions of VS8. All VS9 installations appear to include this library. Adding wldap32.dll is more art than science. If the file is already installed on your system, you can find it by doing a file search in C:\Program Files. Then, you simply add the directory to the library search path as described below. If you don’t have wldap32.dll already installed, download and install MS Windows SDK for MS Server 2008<http://msdn.microsoft.com/en-us/windows/bb980924.aspx>(do a web search to find it). After this is installed, enter the VS IDE options.

Re: [osg-users] ArgumentParser issues on Windows?
Hi Butler;
It is well known problem :) I think your OSG system only compiled in release
mode and you are trying to build this example in debug mode, so program
throw bad_alloc exception. Try to build your example same build type as your
OSG system. If it is released mode you build your example in released mode
or vice versa.

Re: [osg-users] Setting camera target object
Hi Sergey; NodeTracker can be good starting point for you. Search and try to implement. You can look at osgsimulation example. It use this tecnique for tracking aircraft.

Re: [osg-users] Bad OSG geometry
Hi Andrew; osgviewer, take the scene graph and start to accumulate all nodes bounding boxes, by this all accumulated boundingboxes it configure it's viewing area to show you all nodes which are in the screen. So as a result there is some nodes which are not visible on the screen, but viewer take these nodes bounding box on accumulated boundingbox. This is my humble opinion :) Regards. 2009/5/22 Andrew Cunningham > Hi, > There seems to be something wrong with this geometry I have created that > seems to cause OSG some problems.

Hi Robert;
Yes I know we need endline sign on every line break. Actually we put endline
sign by

[osg-users] osg2cpp sample needs a tweak?
Hi Robert; I have realized that when using --shader option in osg2cpp it parses shader file in cpp but it add unneccessary endline sign(\n) every line's end. I think every shaderSource.substr(startOfLine,endOfLine-startOfLine) command should be shaderSource.substr(startOfLine,endOfLine-startOfLine-1) Regards. -- Ümit Uzun ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
