Final project implementation for CIS536 final project.

To run the demos, open the project in Unity. You can open and run any scene in the Scenes folder. The camera view is interactive; right click and drag or use WASD to move.

The external assets used in this project are as follows:

UVWorld by Nakata Nobuyuki, licensed MIT. Modified to use UV2 channel rather than UV1.

KDTree by Vili Volčini, licensed MIT.

Cornell Box (Water) by Morgan McGuire, licensed CC-BY-3.0. Modified to add a bottom to the mesh, creating a sealed object instead of a surface.

Overall photon map algorithm comes from:
