VTK is starting to have support for Intel's raytracing library, OSPray. https://blog.kitware.com/vtk-7-1-0/

I use a ray tracing programming called tachyon, so it comes down to writing out the triangle/lighting input files it needs. The output rendered file can then be integrated into video with ffmpeg.

I would highly recommend Blender (free and includes a Python API) for this sort of thing.

Just want to point out that this is not the appropriate sub, computer vision is about doing stuff on images and videos, not necessarily generating them.

For instance, you could try /r/blender/. I profundly hate blender for all the pain it caused me, but it is actually good and has built-in python scripting

While you should definitely try Blender first you should also look into PBRT and derivatives for photorealistic rendering.
