多种光照效果在纹理映射体绘制中的实现

Implementation of a Variety of Lighting Effects in Texture Mapping Volume Rendering

通过对可视化方法的研究,实现二维和三维两种纹理映射体绘制方法,两种纹理映射方法采用不同的代理几何体生成模式,同时图像也有不同的显示效果。对体绘制中的光照进行研究,实现Phone光照和Cook-Torrance光照增加显示效果的真实性,前者使用较为普遍,实现简单,后者为基于粗糙度的光照模型,对比Phone光照在绘制粗糙图像时更能体现图像表面的粗糙效果。

Through the study of visualization methods, achieves two-dimensional and three-dimensional texture mapping volume rendering, two tex-ture mapping methods use two different proxy geometry generation mode, while the image is also different display effects. Researches the light in the volume rendering and realizes Phone illumination and Cook-Torrance illumination in the effect of increasing the authenticity, the former is more commonly used and simple, and the latter is the light mode based on roughness so it can better reflect the image of the surface roughness than Phone illumination.
