As mentioned, GPUs are not currently fast enough to simulate the finer points of simulating the physics of light in real-time. But you still want to achieve realistic and impressive shading in your games. To work around this problem there is an entire industry worth of tricks, hacks, and approximations designed to give you almost the true result, but with a fraction of the computational expense. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
