基于HLSL的立方体映射技术研究与实现

摘要

计算机仿真领域中,在满足实时性的基础上增强仿真的真实感一直是一个重要的问题.立方体映射技术能够使两者达到一个较好的平衡效果.文中对立方体映射技术的原理进行了详细的研究,并通过HLSL语言在Direct 3D的环境下实现.并且讨论了立方体映射技术的两种改进方法,一种加入了折射效果,一种使用动态地更新立方体纹理的方法.两种方法增强了立方体映射技术绘制下场景的真实感,拓宽了立方体映射技术的适用范围.%It's an important problem to strengthen the reality of simulation on the base of real-time in the field of computer simulation, and cube mapping technique can make them reach the balance. It introduces the principle of cube mapping technique in detail, which is programmed through HLSL language in Direct 3D environment. And it discusses two improving methods of cube mapping technique, adding refractive effects and updating cube texture dynamically. The two methods strengthen the reality of scene which is rendered through cube mapping technique, and expand the application range of cube mapping technique.
