Batch-based visualization of large multiresolution polygonal models

Abstract

In this report we study some techniques for the visualization of large multiresolution polygonal models, some of which do not fit into main memory. We focus our attention in batch-based techniques. The main idea is to represent the model, a given height field or a mesh with no particular topological genus, in a recursive tree-like structure; and to link patches, composed of a few set of triangles, to each of their nodes. To render the model, patches which could reside in secondary memory, are batched to the graphics processor unit (GPU) according to a simply stateless top-down traversal of the structure, guided by a view-dependent error mechanism.
