3-D Coordinate Systems and Geometry

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

• 3-D Coordinate Systems
• 3-D Primitives
• Rectangles
• Vectors, Vertices, and Quaternions
• Face and Vertex Normal Vectors
• Triangle Interpolants
• Triangle Rasterization Rules

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