I predict that after reading this email, you'll be very happy. Check recent git, configure with --cuda-enable-gl=1. (or CUDA_ENABLE_GL=True in siteconf.py, whichever style you prefer) It compiles for me, but is otherwise entirely untested. I would like you to do three things in return: - Test and report back with the result. (I have no way of doing so.) - Write the simplest possible example that does something useful and submit it for inclusion. - Fill out the documentation in doc/source/gl.rst and submit a patch. Also see http://documen.tician.de/pycuda/gl.html. > I saw there was a recent release of codepy; would codepy allow one include > and call the C cuda opengl functions directly or am I misunderstanding how > it works? codepy in principle would allow you to do that, but since PyCuda already builds a Boost.Python extension as part of its build, that would be a rather roundabout and non-portable (Linux-only) way of doing it. > Thanks for your response. You're welcome. :) Andreas
