166 CHAPTER 5: Textures^
Summary
This chapter served as an introduction to textures and their uses. It covered basic
texture theory, how texture coordinates are expressed, how mipmaps can be used for
greater fidelity, and how textures can be filtered to smooth them out. The solar-system
model was updated so that earth now really looks like the earth using a texture map. In
the next chapter, we’ll continue with textures, putting to use the iPhone’s multiple
texture units, along with blending techniques.
