内置着色器指南之标准着色器家族：漫反射着色器

.

Diffuse Properties 漫反射属性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 the this angle, and does not change as the camera moves or rotates around.Diffuse 计算一个简单的（Lambertian）光照模型，光照强度随着物体表面和光入射角之间夹角的角度减小而减小。光照强度仅依赖于此角度，摄像机的移动和旋转无法改变光照强度。
Performance 性能Generally, this shader is cheap to render. For more details, please view the Shader Peformance page.一般情况下，这个Shader渲染代价比较小。更多详细资料请查看着色器性能页面。 【来源：互联网】
