Introduction The MERL BRDF database contains reflectance functions of 100 different materials. Each reflectance function is stored as a densely measured Bidirectional Reflectance Distribution Function (BRDF). Sample code to read the data is included with the database (readBRDF.cpp). Note that parameterization of theta-half has changed. At a Glance The size of the unzipped dataset is ~3.25GB Folder “brdfs” contains the data. Folder “code” contains sample code.
