Hi,
I am adding an osgCompute::Computation node during runtime inside the
updateTraversal of our viewer.
This works fine when added in the first updateTraversal frame, but fails in all
later frames. What am I misunderstanding oder missing? Any hints?
Below the code:
Code:
void osgDAC::DACViewer::updateTraversal() {
..................... some stuff ....................
framecnt_++;
if (framecnt_ == 2) { // this fails, but works for framecnt_ == 1
// osgCompute
setThreadingModel(osgViewer::CompositeViewer::SingleThreaded);
setReleaseContextAtEndOfFrameHint(false);
osg::ref_ptr<osgCompute::Computation> computation =
dacGPU::setupComputation();
osg::ref_ptr<osgCompute::Module> module =
computation->getModule( "osgcuda_warp" );
if( !module )
{
osg::notify(osg::FATAL) << "Cannot find module
identified by osgcuda_warp." << std::endl;
return;
}
module->setUserData( getFrameStamp() );
//osg::notify(osg::NOTICE)<<module->isEnabled()<<std::endl;
// Add computation to scene
getManager()->getGeometryRoot()->addChild(computation);
}
} // UpdateTraversal Done
Thank you!
Cheers,
Johannes[/code]
