Hi all, I am developing an aplication which uses several osg::Geometry for drawing the objects in the scene graph. In order to make the drawing process faster, each osg::Geometry has its own VBO and I modify the VBO vertex with some OpenCL kernels.
So far it is ok, my problem begin when I need to get the modified VBO data. When the OpenCL kernel is executed, the VBO data changes in the GPU memory and I don't know which is it in the CPU. For getting it, I have to copy from the GPU memory to the CPU. That I need is know if there is a method like osg::GLBufferObject::dirty() (which copies the VBO data from the CPU to the GPU) but on the inverse. I know I can solve the problem making a another kernel in OpenCL which copies the data, but I want to know if osg has a method who read the GPU memory. Thank you, Carlos. -- -------------------------------------- Carlos Reig Matut LSyM - Instituto IRTIC Universidad de Valencia Ph. +34 96 354 3639 -- ext. 43639 http://irtic.uv.es/lsym _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
