Abstract
We present a new image-based process for measuring surface reflectance rapidly, completely, and accurately. Requiring only a digital camera, a light source, and a convex curved test sample, our method can measure the BRDF with high resolution and accuracy over a very large domain of illumination and reflection directions. We have verified our measurements both by tests of internal consistency and by comparison against measurements made using a gonioreflectometer.
