Abstract
In this paper we present an uncoupled parallel technique for view dependant continuous level of detail rendering of regular height field terrain. To this end, the terrain is globally modelled by a simple bintree patch-based representation of right-triangles, which is adaptively divided into uncoupled meshes for parallel processing. This is easily performed by uncoupling the mesh along the observer line. Each uncoupled mesh is then recursively approximated to the corresponding level of detail in the terrain. Cracks are avoided by constraining the refinement levels at the boundaries of adjacent meshes. The level of detail is created on-the-fly with a low amount of CPU overhead, allowing a good representation of the terrain and high frames per second performance. This implementation shows significant improvements in CPU load and frames per second performance over the serial method when executed on machines with multiple processors.
