OpenGL Super Bible! Page 385 The Tank Simulator Try the tank simulator as it stood after the last chapter, and compare it to the one for this chapter. This version, which makes heavy use of display lists, consists of many thousands of triangles, and you won t need any benchmarking program or stopwatch to know that the performance has been enhanced! Summary We used this chapter to slow down somewhat and just talk about how to build a three- dimensional object, starting with using the OpenGL primitives to create simple 3D pieces, and then assembling them into a larger and more complex object. Learning the API is the easy part, but your level of experience in assembling 3D objects and scenes will be what differentiates you from your peers. Once an object or scene is broken down into small and potentially reusable components, you can save building time by using display lists. You ll find many more functions for utilizing and managing display lists in the Reference Section. You also learned a simple way to benchmark your OpenGL programs so you can get firsthand experience of the effects of optimizing your code.
