Continuing from his first DVD Global Illumination: Exteriors Christopher Nichols explains how interior global illumination differs from exterior GI. Christopher focuses on the concept of digital sets and explores issues of interior lighting for GI including the variety of light sources that can be used as well as how space plays an important role in lighting. Christopher demonstrates the differences between regular light sources environment light IES lighting area lights and even how geometry and shaders can affect the lighting of a scene. Additionally since bouncing light plays an important role in interior GI this lecture looks at some special techniques such as using V-Ray’s photon mapping and light cache. Christopher also explores the idea of baking lighting into textures which is a useful technique for some situations. With Global Illumination: Interiors you will see the rendering of an interior space in a whole new light.
