| Abstrakt: | This thesis is devoted to the problem of representing bidirectional reflectance distribution functions (BRDF) as ordinary functions and also representing precomputed radiance transfer data of a static scene, because these data (light transfer operator) is among other the derivative carrier of informations about BRDF used. Later we discuss the need and principles of industrial apearance measurement attributes (mainly gloss).
Another part of our work is the implementation of the environment mapping using efficient wavelet rotation. This technique allows dynamic change of lighting, viewpoint and BRDF while preserving all-frequency details. Other implemented feature is the virtual glossmeter. As a feedback to the user it provides gloss unit value measured from the used parametrizable BRDF. In the end we experiment with possible speedup by means of GPU computations and presence of mult-core CPUs.
