| 摘 要： | 基于Cg的Shader技术是当今计算机图形领域中的前沿,结合显卡的硬件渲染技术,对视景系统中的水面流体特效如光照、HDR、凹凸纹理贴图等进行顶点与象素的编程,用极少的系统消耗实现了高性能的视觉仿真效果。和传统的mipmaping算法相比,采用基于Cg的Shader多重分辨纹理的技术可以大大减少多重细节变化所需的纹理数量,实现平滑的纹理细节级别变化。虚拟驾驶模拟器作为相关技术的解决方案和应用实例进行了介绍。 |

| Abstract: | Shader technique based on Cg stands in the foreland of the computer graphics field today,combining with hardware rendering technique of graphic card,which can reduce system burden and get more vivid visual effect through programming vertex and pixel of flow effect of water,such as illumination,HDR,bump maping,and so on.Compared with traditional mipmaping algorithm,the shader technique of multi-resolution texture based on Cg need not get so many textures in order to obtain more smooth mipmaping texture.Finally,the virtual driving simulator is presented as a sample of related solutions and technical applications. |
| Keywords: | Cg language visual system water wave simulation multi-resolution texture |
