Web这个32是高光的反光度(Shininess)。一个物体的反光度越高，反射光的能力越强，散射得越少，高光点就会越小。在下面的图片里，你会看到不同反光度的视觉效果影响：向量的运算 WebBling-phong often uses the term shininess for the specular power. You essentially want to map a roughness of 0 to some very high shininess (say 10000) and 1 to some very low shininess. In the past, I've used: shininess = 100/ (500 * roughness + 0.01) and gotten pretty decent results.

WebJul 15, 2010 · Phong shading approximates this distribution by raising the dot product to an exponent called the shininess factor, with higher shininess giving a more polished shine and lower factors giving a more diffuse sheen. This final specular factor is then multiplied by the specular colors of the light source and surface, and the result added to the ... Phong reflection is an empirical model of local illumination. It describes the way a surface reflects light as a combination of the diffuse reflection of rough surfaces with the specular reflection of shiny surfaces.
