Abstract

An intelligent culling technique is necessary in rendering 3D scenes to allow the real-time navigation in complex virtual environments. When rendering a large scene, a huge number of objects can reside in a viewing frustum. Virtual urban environments present challenges to interactive visualization systems, because of the huge complexity. This paper describes a LOD management (or contribution culling) method for the view-dependent real-time rendering of complex huge urban scenes. From the experimental results, we found the proposed LOD management method effectively limits the amount of objects to put into the rendering pipeline without notable degradation of rendering quality.
