ABSTRACT
We present a technique for sampling the light probe image using variance minimization. The technique modifies median cut algorithm for light probe sampling [Debevec 2005] so that the variance of each region is minimized. The algorithm is fast, efficient, and easy to implement.

HDR light probe sequence resampling for realtime incident light field rendering
SCCG '09: Proceedings of the 25th Spring Conference on Computer GraphicsThis paper presents a method for resampling a sequence of high dynamic range light probe images into a representation of Incident Light Field (ILF) illumination which enables realtime rendering. The light probe sequences are captured at varying ...
Spatially varying image based lighting by light probe sequences: Capture, processing and rendering
AbstractWe present a novel technique for capturing spatially or temporally resolved light probe sequences, and using them for image based lighting. For this purpose we have designed and built a real-time light probe, a catadioptric imaging system that can ...
