Description• In this project, you’re going to implement

Percentage Closer Soft Shadows

• For basic requirements, all you need to do, is to render soft shadow with one area light, and move the light and camera

• For optional tasks, you can(a) implement Variance Soft Shadow Mapping (or more advanced approaches), or(b) enable multiple area lights (maybe with different colors), or (c) use animated models, etc.

Some Useful Tips• You don’t even need to show the light itself, just assume that

it has a certain size. (Hard code is perfectly fine!)

• Esthetics is VERY important. A nice-looking result will earn you more credits for sure. (WHY?)

• Doing optional tasks may give you a small amount of additional scores. Be sure to claim your extra work in your writeup.
