Re: [osg-users] Animation of shared model
Hi, Thilo. I believe you can achieve this by creating new top-nodes of animated model (nodes which contain animation manager callback), sharing model itself, and attaching new animation managers to them (sharing existing animations). Cheers, Sergey. 16.08.2012, 01:01, Thilo Weigel thilo.wei...@atrics.de: Hi, I'd like to place several instances of the same model in a scene and play the model's animation individually on each instance - just like having several nathans standing around and letting each one scratch his head asynchronously to the others. The model is loaded once and assigned to a osg::Group. The model's instances are placed by attaching the osg::Group to different PositionAttitudeTransforms. Similar code as in the osganimationviewer is used to retrieve the model's osgAnimation::BasicAnimationManager which is then added as an UpdateCallback for each PositionAttitudeTransform. Obviously, the animations can now only be played synchronously on all instances. How could I achieve being able to start the animation of each instance individually - for example to let each nathan start scratching its head for a few seconds after clicking on it?

However, after some quick exploration, it seems this is a very tricky task because its Microsoft Surface SDK 2.0 only supports the development using WPF and XNA.

[osg-users] osgAnimations with different models, howto concept
Hi, I'm wondering how to best implement animations with osgAnimation and FBX. I have several FBX models with different animations in takes, verified in MotionBuilder. I create for each model an animation node, inherited from PAT, based on the osganimation example. Then I tried to create animationManagerfinders for each model and start animations with am-playanimations. However, no animatins get started. When I just use the example from osg, I can start each animation by its name. How do I have to design the animationfinder, updatecallback etc to have working independent animations? Thank you!

Re: [osg-users] OSG application onMicrosoft Surfface table?
Hi Helen, I've seen some applications using WPF for their GUI and rendering OSG into a widget. Essentially you can embed OSG into a widget given its HWND. I don't remember the details so you may have to look around and do some testing on your own. On the other hand, if this tech really restricts the technologies that can display onto it, then it may well prevent C++ applications from running (in favor of C#) or prevent OpenGL applications from running at all. This you'll have to discover on your own. The wonders of being an early adopter! :-) In addition, some discussion took place before concerning OSG and multi-touch interfaces, I think some development was done to enable this (in particular for iOS and Android) so multi-touch should be possible in the general sense, but I don't know whether that piece of hardware uses standard protocols to send touch events to applications or if it's a Microsoft-specific thing (probably the latter). Again, you'll have to do some testing, and maybe some modifications to OSG to enable multi-touch on this device. Hope this helps, J-S On 16/08/2012 6:36 AM, Helen Wang wrote: Hi, We recently bought a Samsung SUR40 with Microsoft PixelSense.

Re: [osg-users] MatrixTransform behaving strangely on OSX 1.8 with XCode 4.4
I've recently switch to Mountain Lion, and am getting weird behavior with the
general behavior of OSG, and wanted to see if anyone else had similar issues.
If I apply a MatrixTransform to a node with a translation matrix, the object I
have added to the node becomes a diagonal line. If I instead use a
PositionAndTranslation node, it works as expected. Finally, if I just add the
object to the root node, everything works as expected.
Here's the code I'm using:
Code:
int main(int argc, char **argv) {
osgViewer::Viewer *viewer = new osgViewer::Viewer;
osgDB::Registry::instance()-getDataFilePathList().push_back(../../resources/);
osg::Group *rootNode = new osg::Group;
osg::Node *node = osgDB::readNodeFile(cow.osgt);
osg::MatrixTransform *transformNode = new osg::MatrixTransform;
transformNode-setMatrix(osg::Matrix::translate(osg::Vec3(0, 0, 0)));
transformNode-addChild(node);
rootNode-addChild(transformNode);
viewer-setSceneData(node);
viewer-run();
}
One additional issue, I'm getting occasional crashes with:
Code:
Simulator(74311,0x7fff7c095180) malloc: *** error for object 0x102f1c6a8:
incorrect checksum for freed object - object was probably modified after being
freed.
*** set a breakpoint in malloc_error_break to debug
This occurs in random places, but one example is in 'void
DarwinWindowingSystemInterface::_init()'

I think I found the issue. There were a few previous posts that I thought were unrelated to what I was doing since they referred to using gcc, and I use clang.

[osg-users] Camera manipulation with trackball manipulator
Hi, I'm trying to create a camera at a fixed location that can be rotated using a manipulator. From what I've read, it looks like a trackball manipulator might be the way to do this. The only problem is that when I set it up, in order to keep the camera at the fixed location, the eye and center of the trackball need to be the same. This leads to a bad starting view. Is there any way to get around this while still using a trackball manipulator, or would something else work better? ... Thank you!

[osg-users] osgDB/FileUtils causes compiler errors when building my project
Hi,
I am trying to run some of my c++ code in OpenSUSE 12.1 using OSG. I installed
the RPMs and should be good to go with OSG on that end.
When I build my project though, all I do is #include osgDB/FileUtils and my
compiler (gcc 4.6.2) crashes inside FileUtils saying expected identifier
before '(' token.
I go to the error in FileUtils and it brings me to
enum Value
{
OK,
SOURCE_EQUALS_DESTINATION,
... and so on
}
I have no idea why it is crashing inside of OSG code. I have not modified it
obviously because it's not my code but any help would be appreiciated.
Thank you!

[osg-users] Make osg::discardAllGLObjects() also discard shaders?
How do I get OSG to re-create all GL objects in response to the GL context
being recreated?
I'm trying to get my Android GLES2 app to gracefully handle switching to/from
the Activity where OSG is running, as well as to handle sleep/wake. Whenever
these happen, the EGL context is lost, and all GL objects (buffers, textures,
programs, etc.) are silently deleted.
Therefore, the usual approach is to call glGen*() when the EGL surface is
recreated. Calling glDelete* is counter-productive; the GL objects are already
gone.
I've tried using osg::discardAllGLObjects(), thinking that this will force OSG
to regenerate the GL objects during the next frame(). It appears to correctly
discard the VBOs and texture objects, but it does not discard shaders or
programs.
Code:
void osg::discardAllGLObjects(unsigned int contextID)
{
#ifdef OSG_GL_DISPLAYLISTS_AVAILABLE
osg::Drawable::discardAllDeletedDisplayLists(contextID);
#endif
#ifdef OSG_GL_FIXED_FUNCTION_AVAILABLE
osg::FragmentProgram::discardDeletedFragmentProgramObjects(contextID);
osg::VertexProgram::discardDeletedVertexProgramObjects(contextID);
#endif
osg::GLBufferObject::discardAllBufferObjects(contextID);
osg::Texture::discardAllTextureObjects(contextID);[/b]
osg::FrameBufferObject::discardDeletedFrameBufferObjects(contextID);
osg::Program::discardDeletedGlPrograms(contextID);
osg::RenderBuffer::discardDeletedRenderBuffers(contextID);
osg::Shader::discardDeletedGlShaders(contextID);
osg::OcclusionQueryNode::discardDeletedQueryObjects(contextID);
}
As you can see, this function will discard shaders and programs which have
already been deleted, but as far as OSG knows, none of them have been deleted.
The textures and buffers each have centralized managers, but the shaders and
programs do not.
How should I approach this problem? Is there a straightforward way to fix
osg::discardAllGLObjects() so that it will discard all GL shader objects? Do I
need to track all of my osg::Shader instances myself so I can call
Shader::releaseGLObjects() and Shader::dirtyShader()?
Thanks,
James
