Mipmapping with Bidirectional Techniques

• brief overview about what mips are and how to calculate mip selection in a rasterizer
• explains ray differentials, a technique that can be used for mip selecttion on primary rays
• discussion of problems with ray differentials on other ray types, possible solutions and look at what other production renderers use
• solution using a distance to camera metric and presenting the results by comparing against other techniques
