Page 454 OpenGL Super Bible! Summary In this chapter you ve learned how to texture-map images onto polygons and other primitives using OpenGL. Texturing can provide that extra measure of realism that makes computer graphics so exciting to work with. The OpenGL glTexParameter functions provide many ways to improve the quality of texture images when they are drawn. Mipmapped texture images provide multiple levels of detail that improve rendering quality and speed. Linear interpolation of texture images can improve certain types of textures, such as the sky texture used in the example project. The glTexGen functions can simplify generation of texture coordinates by removing unnecessary or tedious calculations. By removing large amounts of conditional glTexCoord calls, automatic coordinate generation also simplifies programs that must display both textured and nontextured scenes For games and other interactive, animated displays, you may want to support both textured and nontextured displays until accelerated OpenGL graphics boards become more widely available.
