In this chapter, you'll create a 3D object-animation system to move and rotate objects in the world. To draw the 3D objects, you'll use z-buffering to draw polygons in the correct z-order. You'll also create a parser to read 3D objects from OBJ files so you don't have to define lots of polygons in Java code. Finally, you'll put everything together by creating a few simple game ...
