VMD-L Mailing List

Hi,
  When VMD starts up, it automatically detects NVIDIA GPUs
that support CUDA and OptiX (OptiX is the ray tracing development
framework I used to write the existing lightegith GPU version of Tachyon).
If you've got up-to-date NVIDIA drivers, you should see a VMD startup message
that looks similar to this:

Info) Detected 3 available TachyonL/OptiX ray tracing accelerators
Info) Compiling OptiX shaders on 3 target GPUs...

If no OptiX-capable GPUs are seen by VMD, then you won't see the
various "TachyonL-OptiX" renderers listed in in the File->Render menu.

Best regards,
  John Stone
