- peatmoss 8y agoI suppose if the universe is in fact a hologram as some scientists have hypothesized, and we’re just living in a 3d projection then we could say reality is faking it :-) But the current gen video hacks and future raytracing are pretty hard to compare. Raytracing can be an accurate simulation of the physics properties of light. I suppose the biggest caveat is whether you’re doing forward or backward raytracing. Backward raytracing simulates only the photons relevant to the observer. Forward raytracing simulates photons from various light sources, a small fraction of which are observed by the camera. Both are still based on the physical path of virtual photons, which as far as models go, is a pretty solid illusion!
- dgacmu 8y agoWe still fake the surface properties. Skin, for example, involves a lot of subsurface scattering, and we're very far from that. So texture maps it will be for a long time.
