Join Donovan Keith for an in-depth discussion in this video Understanding global illumination, part of Production Rendering Techniques in Cinema 4D.
In this video, we're going to go over what global illumination is as it will come in…handy as we're talking a lot about global illumination in these following videos.…This is just going to be a general overview, and I'll get into more depth about how it…exactly works in future videos. Imagine yourself in a room.…There is a light above and below you have a table.…In the real world, you'd expect to be able to see underneath this table.…However, in the 3D world, that's not always the case.…In this image, we have a very simple area light. It doesn't even have any shadows turned on.…
So, we can't see underneath the table. The lighting seems a bit off.…When we add in shadows which actually are a more complicated calculation for CINEMA 4D,…we can no longer see under the table but we do at least see some shadowing underneath the table.…This is that same image, re-rendered using global illumination.…What global illumination has done is added in bounce lighting and what we're getting…right here is what's called a diffuse depth of 1 so we're getting one bounce.…
