Cook-Torrance Lighting Computation Using Deferred Lighting Techniques
Jiening Wang · Journal of Engineering Graphics · 2004
It plays very important role to generate photo-realistic rendering results for both of virtual reality system and computer games. A fast and powerful method in calculating Cook-Torrance model by using deferred lighting technique is presented. In the first, the principle and characteristics of Cook-Torrance model is introduced, along with the basic idea of deferred lighting techniques. And then a novel lighting computation method of Cook-Torrance model is proposed. We implement fast Cook-Torrance model computation in high quality based on modern graphics hardware acceleration. The experimental result shows it not only renders photo-realistic images but also satisfies interactive requirements.
