Coordinate Systems and Geometry (Direct3D 9)

Programming Direct3D applications requires a working familiarity with 3D geometric principles. This section introduces the most important geometric concepts for creating 3D scenes. The following topics are covered.

• Coordinate Systems (Direct3D 9)
• Primitives
• Face and Vertex Normal Vectors (Direct3D 9)
• Rasterization Rules (Direct3D 9)
• Rectangles (Direct3D 9)
• Triangle Interpolation (Direct3D 9)
• Vectors, Vertices, and Quaternions (Direct3D 9)
