Orthoatlas: texture map generation for dynamic meshes using orthographic projections

Abstract

The generation of a texture map using orthographic projections is performed in a fast and efficient manner. A method to generate texture maps taking significantly less time and also allowing maps to exploit the correlation between content of different frames in time is described herein. The texture mapping is able to be used for automatic generation of volumetric content or for more efficient compression of dynamic meshes. The texture map generation described herein includes ways to generate a texture atlas using orthographic projections. A novel stretch metric for orthographic projections is described, and a merging algorithm is devised to optimally cluster triangles into a single patch. Additionally, packing techniques are able to be used for mesh patches that try to optimize size and temporal stability.
