Join Brian Bradley for an in-depth discussion in this video Understanding photons (GI), part of Learning mental ray in 3ds Max.
…While studies probably fair to say that Final Gather is today the most widely used…of Mental Ray's GI options, it is the system that we will look at here,…Photon Mapping, that has been available for the longest time.…In fact, although Final Gather is today used as a complete GI solution in…its own right,…it was initially introduced as a tool to help smooth out photon map renders.…Now Photon Mapping unlike final gather is not a view dependent, but…is rather a scene-dependent GI technique.…
This is because Photons are shot or traced not from the rendering camera in a scene,…but from the light sources themselves,…providing of course that option on the light has been enabled.…This means that once a photon solution has been calculated, it can be saved to disc,…and the rendering camera moved anywhere inside the environment we like,…without causing any problems at all for the GI solution at render time.…Again, and let's walk through the basics of how a photon GI solution is created,…just so that we're clear on how the technology is working.…
