| 摘 要： | 在研究光照模型的基础上,重点分析了延迟光照技术和高动态范围(HDR)技术,并研究了基于高动态范围技术的延迟光照技术,在延迟光照的后处理阶段引入高动态范围技术,发挥两者的优点,基于GPU实现了加速绘制。实验证明,使用基于高动态范围技术的延迟光照技术,表现的场景更加真实,细节表现更加丰富。在延迟光照中,使用高动态范围技术,虽然降低了绘制速度,但仍然达到了25FP/s。

| Abstract: | 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. |
