Paper Abstract

In order to render the virtual terrain environment in real-time, a view-dependent continuous LOD algorithm is presented in this paper. We analyze the regularity of the regular grid Digital Elevation Model and employ three view-dependent criteria to reduce the complexity of the terrain in real-time: (1) screen space error; (2) view-frustum intersection; (3) node orientation. The experiment results indicate that this algorithm can attain a much higher frame rate in rendering the virtual terrain environment, as well as in maintaining the visual quality.
