Real time global illumination (GI) is a difficult and steadily researched area. Advances in the field could potentially benefit virtual reality applications by increasing users' sense of presence. In immersive virtual environments (IVE) like CAVEs, applications must support perspective-corrected stereoscopic rendering. Dmitriev et al. [2004] performed GI in(More)
Large scale terrain rendering in real-time is a well known problem across the computer graphics community which has garnered many solutions relying on dynamic level of detail changes to the terrain. These algorithms typically fit into two categories: in-core and out-of-core. Out-of-core algorithms usually require data to remain static, thus disallowing(More)
Visualizing planetary terrain presents unique challenges not found in traditional terrain visualization: displaying features that rise from behind the horizon on a curved surface; rendering near and far surfaces with large differences in scale; and using appropriate map projections, especially near the poles. Projective Grid Mapping (PGM) is a hybrid(More)
For many years, introductory Computer Science courses have followed the same teaching paradigms. These paradigms utilize only simple console windows; more interactive approaches to Computer Science education are possible. Just as scientific visualization aides the researcher in drawing new conclusions from data, a visual tool that allows the visualization(More)
