The main goals of the project are enhancement of realism in virtual environments via careful simulation of lighting, and application of parallel processing techniques for speeding up computation. The research was focused on hierarchical cluster-based radiosity algorithms and experimental validation of lighting simulation algorithms. Also, several parallel algorithms for extracting ridge and ravine geometric features of a surface were developed and implemented. The study on hyperworld modeling has been conducted and the direct mapping between multimedia information worlds and real worlds is considered as one of the basic characteristic of a hyperworld.
