摘　　要：为了理想化物体表面反射模型,通过辐射度学和球面三角公式推导出条形光源、均匀光源和半球均匀光源照射下的朗伯体场景辐射亮度,进而得到了3种光源下的朗伯体表面反射模型.In order to idealize the reflection model of object surface,the scene radiance of the Lambertian object illuminated by the strip light source,the uniform light source and the hemispherical uniform light source is derived by the radiance and the spherical triangle formula,and then the Lambertian surface reflection model in three kinds of light sources is obtained.

关 键 词：表面反射模型 朗伯体 光源 从明暗恢复形状算法 双向反射分布函数
