Chapter 8. Gleaming the Cube
This chapter presents an assortment of graphics topics, including skybox rendering, environment mapping, fog, and color blending. The first couple effects share a common theme: They are implemented through texture cubes. And all the material takes you farther along the path of graphics enlightenment (pun intended).
Texture Cubes
A texture cube (also known as a cube map) is a set of six 2D textures. Each texture corresponds to a face of an axis-aligned cube (typically) centered on the world space origin. These textures can be stored individually or can all reside in the same file using a format such as DDS (discussed in Chapter 3, “Tools of the Trade”). Figure 8.1 shows a texture cube stored in a single file, with ...
