漫射光映射Diffuse light maps

亚光表面具有漫反射光。Matte surfaces have diffuse light reflection. 漫反射光的亮度取决于与光源的距离以及表面法线与光源方向矢量之间的角度。The brightness of diffuse light depends on the distance from the light source and the angle between the surface normal and the light source direction vector. 纹理光照贴图可以模拟复杂的漫射照明。Texture light maps can simulate complex diffuse lighting.

光线计算模拟的漫射光线效果仅会产生常规效果。The diffuse lighting effects simulated by lighting calculations produce only general effects. 你的应用程序可以使用纹理光线映射模拟更复杂的漫射光线。Your application can simulate more complex diffuse lighting with texture light maps.
