Couple of questions if you have the time. When you say luminance() during variance variance estimation, what does that signify? Is it a dot product to get a scalar value to use with weight calculations? And also during weight calculations, I am assuming #curDepth is from currentFrameGBuffer values and #depth is previousFrameGBuffer values?
