摘要
我们分析了Ward的经验反射模型的能量平衡，并计算了Ward的蒙特卡罗重要采样在Radiance Lighting Simulation and Rendering System中的分布。这两个结果都表明Ward提出的双向反射分布函数的不同归一化。
An Improved Normalization for the Ward Reflectance Model
We analyze the energy balance of Ward's empirical reflection model and calculate the distribution of Ward's Monte-Carlo importance sampling used in the Radiance Lighting Simulation and Rendering System. Both results suggest a different normalization of the bidirectional reflection distribution function proposed by Ward.
