Real-time Image-Based Lighting

(Recently I cleared the background to black and uploaded a video. Dec, 2012)

I visited Paul Debevec's website many times and read many of his papers. However, not until recently I started from scratch to implement IBL myself.

OpenGL/GLSL 4.2 and OpenEXR 1.7 is used. Uffizi light probe is downloaded and then transformed to cube-face environment maps using exrenvmap, which is one of the tools inside OpenEXR release.
