A Short Discussion About Light, Part 07
Dr. Sassi shows how important the surface details of a model can be when trying to capture realism in an image. In this video Dr. Sassi shows how important the surface details of a model can be when trying to capture realism in an image, introducing the concept that the less detailed a surface is the less it will change received light. This is presented by comparing several different models with no surface details, and with appropriate detail added, either as a texture or modeled. |

Industrial Modeling - Holes, Part 14
Dr. Sassi shows you how to create reflections with distance based falloff. In this video Dr. Sassi shows you how to create reflections with distance based falloff.
