Shader Writing in Open Shading Language: With RenderMan® Examples - Softcover

Inhaltsangabe

Incorporating both historical techniques and the most recent developments in computer graphics, Shader Writing in Open Shading Language is a treatise on OSL shader writing and shader development that hopes to remedy the current lack of material on this important area of technical and artistic expertise.

It begins by covering the entire range of independent variables upon which all shaded pattern generation is based. Building on that foundation, every fundamental pattern generation, conversion, and modification category is described with clear and practical examples. Each topic is presented in a progression of chapters that begin with the fundamentals and progress to more complex shaders illustrating more advanced techniques that build on the previously covered material.

In addition, these important topics are also covered:

• Shader user interface design and parameter widgets
• Color, color models, color spaces, and color transformations
• 2d and 3d spaces and their transformations
• Texture patterns
• Ray tracing for pattern generation
• Displacement and bumped shading normal generation
• Shader organization, building, and deployment
• Shader execution and debugging
