== Installation == I did the entire assignment remotely on myth.stanford.edu. Everything went smoothly. == Experimentation == Setting the picture to 200x200 and the sample per pixel to 2, on myth it's pretty fast. Also I wrote a script -------------------------- !/bin/sh pbrt lighting.pbrt exrtotiff lighting.exr lighting.tif gnome-open lighting.tif -------------------------- to make it even faster. [[WangQiqi_A1_config4_color.png]] To seperate effects of the 4 light sources, I used different color for each light source.
