Fotorealistické zobrazování 3D scén

This thesis proposes a concept of sampling, especially for path tracing like algorithms, for faster convergence of the scene, using a local radiance approximation in the scene with hemispherical harmonics, which allows more effective way of ray casting on the given surface. In the first part, the basics of photorealistic rendering are introduced together with commonly used algorithms for image synthesis. The mathematical apparatus used in this thesis is defined in the second part of the thesis. Subsequently, existing solutions in this area are presented. The following chapter summarizes state-of-the-art methods in this branch. The rest of this thesis is focused on proposal and implementation of already mentioned extension.
