Texture Mapping Techniques
Texture mapping is a powerful building block of graphics techniques. It is used in a wide range of applications, and is central to many of the techniques used in this book. The basics of texture mapping have already been covered in Chapter 5 and serves as a background reference for texture-related techniques.
The traditional use of texture mapping applies images to geometric surfaces. In this chapter we’ll go further, exploring the use of texture mapping as an elemental tool and building block for graphics effects. The techniques shown here improve on basic texture mapping in two ways. First, we show how to get the most out of OpenGL’s native texturing support, presenting techniques that allow the application ...
