Hi Steve and Shintaro, Shintaro is right, PyMOL's ray tracing is CPU only. It runs parallel on multiple CPU cores.
Our graphics development over the last years was focused on getting the real-time OpenGL rendering (which uses the GPU heavily) as close to the ray traced images as possible. Lighting, antialiasing, and pixel-perfect sticks and spheres should be identical with "draw" and "ray". There are still some gaps, the ray tracer has shadows, better multi-layer transparency, and outline modes (https://pymolwiki.org/index.php/Ray#Modes ) that we don't have in real-time yet. For movies, I would certainly consider "draw" rendering a good option, unless you need shadows or better transparency. # write out PNG images mpng prefixdraw, mode=1, width=1280, height=720 mpng prefixray, mode=2, width=1280, height=720 # write out MPEG 4 (requires ffmpeg) movie.produce draw.mp4, mode=draw, width=1280, height=720 movie.produce ray.mp4, mode=ray, width=1280, height=720 Cheers, Thomas On Mon, Oct 29, 2018 at 1:48 PM Shintaro Aibara <shintaro.aib...@gmail.com> wrote: > > I am under the impression that ray tracing is an entirely CPU process in > pymol.
