Multiple Cook-Torrance lobes are good enough to represent metallic car paint material in an environment.
And till now, I have almost known how to implement the mia_material, mi_metallic, mi_carpaint .
Check the code at Ortholab.
多个CT高光已经可以足够模拟金属汽车游戏的效果了。
到现在为止，我已经差不多完全知道mia_material、mi_metallic、mi_carpaint的内部实现或者是替换实现了。
代码在Ortholab上有。
