Computer Graphics And Visualization

METU Computer Graphics and Visualization Research Group (CGV) is formed to study various research areas of computer graphics and visualization in 1996. More specifically CGV has been involved in the following specific research areas: Game Technologies: massively multiplayer online games, serious games, architectures; Geometrical Modeling: multiresolution, virtual sculpting; Global Illumination and Rendering: ray tracing and radiosity, occlusion culling; GPU Programming: gpu ray casting, volume rendering, smoke generation; Modeling and Simulation: C4ISR systems, agent based simulations, driving simulators; Visualization for different domains: volumetric objects, bioinformatics, cultural heritage, military and road safety.
