1. I want to get .dat file to generate images of arbitrary resolution. But in VMD (Linux) I can only see option for that in normal tachyon. i.e. TachyonL-Optix gives images directly. is there anyway to use Tachyon with GPU to generate .dat files? Using OSPray? I have seen VMD site claiming it can run on massively parallel supercomputers, is that done using only mpi?

2. How to tell tachyon to use optix renderer for generating images using GPU from command line? i.e. what is GPU equivalent of tachyon -res xxx yyy ?
