Out-of-Core Constructing and Interactive Rendering of Multiresolution Representations for Massive Meshes

This paper proposes a novel approach for constructing and rendering out-of-core multiresolution representation for massive polygonal meshes. It keeps the details of the original model by adaptive octree partitioning of the mesh bounding box, and reduces the average cache miss rate through mesh layout optimization for triangles contained in the octree node. At rendering stage, the multiresolution representation structure is refined and rendered with view-dependent LOD selection. At last, the approach employs data prefetch strategy to hide I O latency and then further improves the rendering performance. Experimental results show that the proposed approach is superior to similar MRMM algorithms in term of rendering speed and capability of preserving details.
