Web据我所知，这四个应该是指微面分布函数（Microfacet Distribution Function）。. 微面分布函数是微面模型中的一项，而微面模型是用来模拟光在物体表面反射的一种数学模型。. 根据该数学模型推导出的计算Lo的公式如下：. 然后里面的D项就是微面分布函数。. 它们的 ... WebBlinn-Phong is a slight adjustment of the Phong model you saw in the lighting section. It provides more plausible or realistic specular reflections. You'll notice that Blinn-Phong produces elliptical or elongated specular reflections versus the spherical specular reflections produced by the Phong model. In certain cases, Blinn-Phong can be more ...

This is with the same shininess as before; because Blinn-Phong doesn't have a Fresnel term, the cos(θ) fix causes the intensity to fall off dramatically at grazing angles. But the discontinuity is gone, at least. This is fixed Ward, with the same shininess as the 2nd image before.

WebAug 16, 2012 · Did some testing using the FormFonts tester ball to compare the 3 shaders and their affect on render time. Phong seems to render faster and blur reflections a bit less. Ward, from what I am told, is good for metals but render times are much longer.
