WebPhong光照模型. 之前说过，游戏场景中计算光照时，需要考虑光源、模型材质和观察方向三方面的因素。很多物理学家、数学家根据这些因素，再结合真实物理世界光照效果的经验，总结出几种非常经典的光照模型，比如说兰伯特（Lambert）、环境光（Ambient）、Phong、Blinn-Phong、PBR等等，其中最经典的 ...
WebJan 25, 2024 · Blinn-phong is a variation of the Phong equation that is more efficient and the results are almost the same. In some situations, Blinn-phong is even better. The only difference with Phong is that Blinn-Phong, instead of using the reflected vector R to calculate the specular component, it uses the halfway vector H: WebBlinn-Phong 反射光模型. 该模型能够简单地描述物体表面对光的吸收和反射，使物体表面呈现出不同的明暗程度，但其不是最真实的一种反射光模型。 引入该模型的原因：它能够 …
