WebThe moments of the raised cosine distribution are somewhat complicated in the general case, but are considerably simplified for the standard raised cosine distribution. The standard raised cosine distribution is just the raised cosine distribution with = and =. Because the standard raised cosine distribution is an even function, the odd moments ... WebYou can also calculate a ratio of Weighted and Numeric Distribution, so-called Coefficient of Distribution Efficiency. Coefficient of Distribution Efficiency = Weighted Distribution ÷ Numeric Distribution (e.g. in our Example it is 45,5%÷60% = 0,758) If Weighted Distribution is lower than Numeric, the coefficient is less than 1. proof copies of booksWeb1 Answer Sorted by: 12 You always need to multiply by the cosine term indeed (that's part of the rendering equation). Though when you do indirect diffuse using ray-tracing and thus monte-carol integration (which is the most common technique in this case), you have to divide the contribution of each sample by your PDF. This is well exampled here. lacewing order and family
