HDR-Based Deferred Lighting Technology

With the developing of the compute game industry and virtual reality technology, people need realistic effect in 3D scene in the runtime interactive system, such as game software, simulation of fly and simulation of battle. To improve the realistic effect in complex 3D scene, we study geometry scene, material and illumination. This paper focuses on illumination model. Deferred lighting and HDR technologies are analyzed, and a combination approach is proposed. Experimental results show that HDR-based deferred lighting technology can help to represent more detailed scenes. Even though this approach slows down the rendering speed, it is still above 25FP/s.
