Distortion Minimization and Continuity Preservation in Surface Pasting

Proceedings of Graphics Interface 2003, Halifax, Nova Scotia, Canada, Canada, 11 - 13 June 2003, 193-200
We introduce the Camera Aware View-dEpendent Continuous Level Of Detail (CAVECLOD) polygon mesh representation. Several techniques recently have been developed that use a hierarchy of vertex split and merge operations to achieve continuous LOD. These techniques exploit temporal coherence. However, when multiple cameras are simultaneously viewing a polygon mesh at continuous LOD, the exploitation of temporal coherence is difficult. The CAVECLOD mesh representation enables multiple cameras to simultaneously exploit temporal coherence. Texture coordinates and normal vectors are preserved and the algorithm uses Microsoft DirectX Vertex Buffers and Index Buffers for efficient rendering. Interactive frame rates are achieved on large models on commercially available hardware.
