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。 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.
