| 摘 要： | 实时水面效果可以大大增强虚拟现实系统的沉浸感。基于Cg图形硬件开发语言以及OpenGL,综合利用P-buffers技术、凹凸纹理技术、投影纹理技术以及动态纹理技术模拟了一个实时的、包括反射、折射、水面波动、太阳波光以及Caustics等效果的水面环境。该方法仅需要两个三角形单元来构建水面。

| Abstract: | The effect of real-time water surface can consumedly enhance the immersion characteristic of virtual reality system.Based on Cg and OpenGL,some technologies including P-buffers,Bump Mapping,Projective Texture Mapping and Dynamic Texture Mapping were used synthetically to simulate a real-time water surface.In this simulation,some effects,such as reflection,refraction,wave,sun light reflection and caustics,were realized and the water surface was constructed only by two triangles. |
