Re: [osg-users] release and flush GL Objects?
Another problem is, that nodes which are currently not connected to the sceneview/camera won't release their GL objects.

Well there isn't much the core OSG can do about this. If you go detect objects from the Viewer and it non longer knows anything about it then its doesn't have any chance to clean things up for you. You'll need to manually handle this yourself. Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] release and flush GL Objects?
Hi Robert, We are using the osgViewer::Viewer to integrate our app with Java using jogl to create a GL context and GraphicsWindowEmbedded class. In the past using the SimpleViewer we had the call releaseAllGLObjects(), which internally calls to sceneView-releaseAllGLObjects() and some more stuff. Is there any similar call inside osgViewer::Viewer?, with jogl there is an special Panel that use internally pbuffers to create the context, but when we resize the component the context is lost, so calling releaseGLObjects did the trick for us, but now I don't find a good way to get the same things working. I tried with viewer-getCamera()-releaseGLObjects(); but doesn't work. Maybe adding a releaseAllGLObjects method in View, or in Viewer is a good place. thoughts?

Hi Rafa, I'm not 100% sure it will work but try: viewer-getSceneData()-releaseAllGLObjects(); Robert.

Sorry,

Is the call I was thinking of.
releaseAllGLObjects method is only inside SceneView class
which is not easily accessible in the osgViewer::Viewer.
You get get the SceneView via the Renderer object which is attached
the Camera in 2.1.x.
However, you shouldn't need it.
All SceneView::releaseAllGLobjects() does is:
void SceneView::releaseAllGLObjects()
{
if (!_camera) return;
_camera-releaseGLObjects(_renderInfo.getState());
// we need to reset State as it keeps handles to Program objects.
if (_renderInfo.getState()) _renderInfo.getState()-reset();
}
And all SceneView::flushAllDeletedGLObjects() does is:
void SceneView::flushAllDeletedGLObjects()
{
_requiresFlush = false;
osg::flushAllDeletedGLObjects(getState()-getContextID());
}
So you could try:
viewer.getSceneData()-releaseGLObjects(); // or getCamera()...
viewer.getCamera()-getGraphicsContext()-getState()-reset();
osg::flushAllDeletedGLObjects(0);
