An Algorithm for Multi-resolution Dynamic Terrain

The real time visualization of the dynamic terrain is the key point in the development of the vehicle training simulation system.The character of existing level of detail(LOD) terrain algorithms were studied.In order to meet the dynamic terrain requirements and adapt to the current system graphic hardware performance,a novel multi-resolution dynamic terrain algorithm based on GeoMipMap algorithm was proposed.The novel algorithm can better generate continuous LOD terrain model,and support real time changes of height field and brightness.The experimental result proves the novel algorithm applied to visualization system to be feasible and efficient.
