Idea: Make the rough shapes and models in Blender. Import into POV and do the patterning there, and the 3D textures, with math models. That would be a great combo!
These are two totally different paradigms within 3D rendering. Also if I'm not mistaken you can take Blender scenes and render them with POV-Ray. The texturing and pattern creating in POV-Ray is unmatched. It's really, really great, even though you have to script it. And the fact that it's scripting first, makes it so you can do far more interesting math stuffs with POV. But ofc Blender is getting to be the industry standard these days, and it's pretty great for modelling, if not the greatest.
why would you even bother to compare these two? also there are thee rendering engines in blender, workbench, cycles, and eevee. this video is literally useless
