Implementation of setgpu.lib #144

Closed XiaoXuan42 closed 1 year ago

XiaoXuan42 commented 1 year ago

I have trouble in getting opengl to work on different gpu in my project and I want to learn from your practice. If I'm right nvdiffrast uses setgpu.lib to select gpu and the source code is missing. Can you provide some guides on how to select gpu for opengl on linux(ubuntu)?

That library is Windows-only. On Linux, nvdiffrast uses EGL's functionality to enumerate display devices and select the one that has the correct Cuda device index. While it's not exactly what you're looking for, you can find the function in nvdiffrast/common/glutil.cpp, line 265. I hope this helps you forward.

Thank you! I'll search for equivalent api of opengl.
