Brdf ramp texture

Web纹理映射技术（texture mapping） 逐纹素(texel)的控制模型的颜色，实现把一张图“黏”在模型表面。 纹理映射坐标（texture-mapping coordinates） 建模时用纹理展开技术把纹理映射坐标（UV坐标）存储在每个顶点上，用一个二维变量（u,v） 表示。u，v通常被规划到[0,1]。 Webanalogy to the BRDF, we’ve introduced the term BTF to describe the appearance of texture as a function of illumination and viewing direction. Specifically, the BTF is a texture image parameterized by the illumination and viewing angles. …
