Hi,
I find it is very time-consuming if osgCUDA::Geometry is added too much
PrimitiveSet. But if replace osgCUDA::Geometry with osg::Geometry, it is very
fast even if osg::Geometry is added the same number of PrimitiveSet.
for example,
osgCuda::Geometry* geometry = new osgCuda::Geometry;
for (unsigned int i=0;i<60000;i++)
{
geometry->addPrimitiveSet( otherGeometry->getPrimitiveSet(i) );
}
otherGeometry is a osg::Geometry, a model.
the running time is over 10 minutes.
but if I use osg::Geometry, the running time is only several seconds.
So I want know the reason and how to improve.
Thank you!
Cheers,
Zhen
