Unified points beams and paths: image comparison

This supplemental material contains an image comparison of the three scenes from the UPBP paper: Still Life, Mirror Balls and Bathroom.

Note that the images showing unweighted sampling technique contributions have skewed relative brightness. This is because they double-count energy differently for different types of paths, and their exposure has been manually adjusted. The important thing to observe is the noise in the unweighted contributions which is significantly diminished by the adaptive MIS weighting, as seen in the weighted contribution images.

Note: The images on the three web pages above take approx. 30MB altogether, so they may take some time to fully load.
