Project 02 - Shadow Casting
In this project, I have done all the required tasks. Below are the renders I generated.
With GPU acceleration, regular lighting images (point light, spot light and fake shadow with "transparent" object) are rendered in real time.
For the area lights, over 1024 (32x32) samples are used in generating soft shadows. The images are rendered in a progressive way and the typical running time for an image with 1200 shadow samples is 30 seconds.
