Real-time Terrain Rendering and Processing

Shiben Bhattacharjee (homepage)

Terrains are of great interest in flight simulators, geographic information systems and computer games. In computer graphics, terrain rendering is a special case because of their bulk. They cannot be handled as a single entity like other object models like teapots, cars and crates. Triangulated irregular networks of terrains are typically created by simplifying a dense representation. Such representations are popular in GIS and computational geometry. The recent trend in graphics is to use regular grid representations since they go well with today�s graphics hardware. We explore different representation techniques to render terrains in this thesis. We look into real-time rendering, editing, and physical interaction with external objects on terrains. We also present a representation for efficient rendering of spherical terrains. Apart from rendering terrains realistically, we develop a method to render terrains artistically with painterly abstraction as well.. (more...)
