Re: Question about "Five Common Misconceptions about Bias in

Yes this is the geometric term from Veach PhD. As Toshiya said, you need to importance sample the geometric term i.e. 1/r^2 has to "go away" in the estimator. This is trivially the case in path tracing or less trivially, with multiple important sampling for bidirectional path tracing. With...
