Image Synthesis Homework 3


CPSC 6650 Program 2 Create a box filtered image at the same resolution as in program 1. Use the following sampling strategies for 64 samples per pixel: regular, random, jittered, mult-jittered, Hammersley. Note that code for the last two are available on the net and you can use it. In addition to the images, create images showing the absolute error, and compute the average relative error.
Extra Credit Use a Dobkin/Mitchell optimized pattern as well.
