Adaptive BRDF Measurement Method Using Between-Model-Parameter Variance

Summary

The bidirectional reflectance distribution function (BRDF) measured from a real object is one of the most important factors for photorealistic rendering. However, not only the acquisition time but also the estimation time becomes so long due to the need for an enormous number of reflectance samples and calculations. In this research, we propose a method to shorten the measurement time by adaptively determining the measurement strategy after each sampling.
