Addison-Wesley has provided OpenGL.org with a sample chapter from The OpenGL Programming Guide 4th Edition (Redbook) for download (1.2MB PDF). This is the must-have book for every OpenGL programmer. The sample Chapter 9 covers texturing mapping. After reading this chapter you should be able to:
- Specify texture images in compressed and uncompressed formats
- Control how a texture image is filtered as it’s applied to a fragment
- Create and manage texture images in texture objects and, if available, control a high-performance working set of those texture objects
- Specify how the color values in the image combine with those of the fragment to which it’s being applied
- Supply texture coordinates to indicate how the texture image should be aligned with the objects in your scene
- Generate texture coordinates automatically to produce effects such as contour maps and environment maps
- Perform complex texture operations in a single pass with multitexturing (sequential texture units)
- Use texture combiner functions to mathematically operate on texture, fragment, and constant color values
- After texturing, process fragments with secondary colors
- Perform transformations on texture coordinates using the texture matrix
- Render shadowed objects, using depth textures
