eBook Description:

Essential Guide to RenderMan Shading Plugin Development: Understanding Bxdfs

Understand the fundamentals of Bxdf plugins for RenderMan 21+, both the technical details and API architecture. The main goal of the book is to enable technical artists, hobbyists, and students in using the noncommercial (NCR), free RenderMan edition. RenderMan is an industry standard for rendering software. It has been used for every Pixar film to date and numerous other projects. RenderMan 21, and all subsequent versions, use Monte Carlo path tracing. This change has necessitated the use of C++ plugins in place of the RenderMan Shader Language (RSL). Because of this, writing Bxdfs now requires knowledge of Monte Carlo integration, probability density functions, and the RenderMan C++ API.

• C++ development for Bxdfs
• Fundamentals of the rendering equation
• Monte Carlo integration

Essential Guide to RenderMan Shading Plugin Development specifically addresses writing RenderMan C++ materials. It explores the mathematical models of representative Bxdfs while drawing parallels, when helpful, to earlier RSL implementations. It also includes an overview of Integrators, providing further context for modern RenderMan programmable shading.
