Terrain is a client/server system to visualize terrain from a first person view. The whole project is written using J2EE and Java 3D. The system is designed to visualize different first person graphics, altough so far only a server that could visualize terrains is implemented. The terrain model is stored in multiple resolutions depending on the distance of the viewer. This produces fast, high-quality images from all distances. Very large terrain models are also supported that could even exceed main memory.
