This book uses examples in OpenGL and OpenGL Shading Language to present the theory and application of shader programming. It explains how to program graphics shaders effectively for use in art, animation, gaming, and visualization. Along with improved graphics and new examples and exercises, this edition includes a new chapter on converting a fixed-function OpenGL program to a shader-based OpenGL program. It also explains how best to use tessellation shaders, illustrates the importance of the invariant qualifier for multipass rendering, and presents new applications, including terrain bump-mapping and LIDAR data.

Zusammenfassung
Graphics Shaders: Theory and Practice is intended for a second course in computer graphics at the undergraduate or graduate level, introducing shader programming in general, but focusing on the GLSL shading language. While teaching how to write programmable shaders, the authors also teach and reinforce the fundamentals of computer graphics. The sec
