漫射 (Diffuse)

注意：Unity 5 引入了标准着色器来取代此着色器。

Diffuse Properties

Diffuse computes a simple (Lambertian) lighting model. The lighting on the surface decreases as the angle between it and the light decreases. The lighting depends only on this angle, and does not change as the camera moves or rotates around.
