Coordinate Systems and Geometry

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
• Primitives
• Face and Vertex Normal Vectors
• Rasterization Rules
• Rectangles
• Triangle Interpolation
• Vectors, Vertices, and Quaternions

These topics provide high-level descriptions of the basic concepts employed by a Direct3D application. For more information about these topics, see Further Information.
