I had this idea myself, but thought I'd see if anyone had actually tried it. I'm
currently running an "orbit" around a scene then using python and EXIFTool to
insert exif data into the images. Meshroom isn't liking the images without it,
but you need a "sensor width" value (as you would with a real camera) but I'm
not sure what it would be. In theory it's either zero or maybe its the size of
the image plane. I certainly think it's possible to meshify a POV ray object.
You could change the texture to a purely diffused one, maybe with a checkboard
pattern. For a complex scene you could maybe render each part independently.
