I'm not sure if this addresses your problem exactly (I'm not very familiar with
osgPPU):
If I need to adapt my viewport and to resize my RTT-textures I use something
like this:
Code:
_cam->setCullCallback( new fboAttachmentCullCB( this ) );
void fboAttachmentCullCB::operator()(osg::Node* node, osg::NodeVisitor* nv)
{
osg::Camera* fboCam = dynamic_cast<osg::Camera*>( node );
osgUtil::CullVisitor* cv = dynamic_cast<osgUtil::CullVisitor*>(nv);
if ( fboCam && cv)
{
cv->getCurrentRenderBin()->getStage()->setFrameBufferObject(NULL); //
reset frame buffer object - see RenderStage::runCameraSetUp for details, the
fbo has to be created again
cv->getCurrentRenderBin()->getStage()->setCameraRequiresSetUp( true );
// we have to ensure that the runCameraSetUp will be entered!
}
traverse(node,nv);
}
Best regards,
Mick[/code]
