A Median Cut Algorithm for Light Probe Sampling (bibtex)
by Paul Debevec
Abstract:
We present a technique for approximating a light probe image as a constellation of light sources based on a median cut algorithm. The algorithm is efficient, simple to implement, and can realistically represent a complex lighting environment with as few as 64 point light sources.
