We introduce a framework for streaming geometry in VRML that eliminates the need to perform complete downloads of geometric models before starting to display them. Starting with a level-of-detail (LOD) hierarchy of the geometry generated by any polygon reduction method, we build a multiresolution data structure for efficient rendering. Our data structure requires only about 10 percent additional memory on top of the full detailed model and can be used in combination with any mesh compression method for storage or transmission of the LOD hierarchy through a network. Our framework also suits viewpoint-dependent refinement.
