Vertex and Pixel Shaders, Part 2

• Input and output of a vertex shader and a pixel shader
• Data types, swizzling, and write mask
• Built-in functions
• Standard coordinate frames; conversions between them; matrices supplied by the framework
• Defining a user interface inside an .fx file; connecting fields to objects
• Per-vertex lighting
• Deformation effects; correcting the normal vector after defomation
• Using several passes: backface culling, z buffer, alpha blending
