Multiresolution Modeling of 3D Maps

DOI

説明

Three-dimensional (3D) urban models, come with huge data size and their simplification is often needed for efficient streaming, rendering and visualization. In this paper, we present a strategy for organization of this data such that the models of reduced resolution can be readily created. Simplification techniques for different types of objects in the urban models are presented and are used to represent them at different levels of detail. Objects are classified based on their importance relative to other objects in the model, and based on this classification, a suitable level of details of each object is determined for inclusion in the model of reduced resolution
