Abstract
Photo-realistic terrain generation in real-time is critical to the success of many real-time graphics and virtual reality applications, such as flight simulators. This thesis presents algorithms to generate virtual terrain and render the terrain in real time in graphics processors. The terrain geometry is generated by the Fractional Brownian Motion algorithm with the initial shape controlled by user input. Instead of using expensive satellite image, the ground layer texture is synthesized by a model cover layer, added onto it are several small textures that can be tiled seamlessly. The model cover layer provides a 3D model of the terrain with a general distribution function to include realistic conditions to the terrain with multiple instances of ground features scattered in. The thesis also discusses the algorithm to use programmable GPU to create real-time shadow and blend the ground layer texture in the shader program.
