An Algorithm for Real-Time Rendering of Terrain Surface Based on Continuous Level of Detail

WU Ya dong, \ LIU Yu shu (Department of Computer Science and Engineering, Beijing Institute of Technology, Beijing100081)  
To investigate real time rendering of terrain surface, improve the speed of rendering and the fidelity of simplification, the algorithm taking the distance from vertex to average plane as the error metric and progressive meshes based dynamic simplification was used, which provided view dependent simplification of the model. The use of triangle strips and quickly culling faces outside the view frustum also contributed to fast rendering of terrain surface. On a PⅡ300 machine the algorithm achieved a speed of 71 ms per frame, and the rendering quality could be accepted. The error metric based on distance from vertex to average plane can produce high fidelity of dynamic simplification, and reduce the complex computation when rendering.
