In this paper we present a novel LOD based rendering approach that integrates geometry based and image based LOD mechanisms in one system. We assume that every LOD object in the scene is represented by a textured polygonal mesh. In a preprocess we generate a continuous multiresolution model for all LOD objects. During runtime we first check for every LOD object if an appropriate cached approximation generated for former frames is available. If not, we extract a new suitable approximation out of the objects continuous multiresolution model depending on view-dependent criteria. After that, we replace this adaptive geometry-based approximation by an image-based impostor if this is reasonable and efficient. The selected approximations of LOD objects are used for rendering the next frame
