Abstract: Many mesh parameterization algorithms have focused on minimizing distortion and utilizing texture area, but few
have addressed issues related to processing a signal on the mesh surface. We present an algorithm which partitions
a mesh into rectangular charts while preserving a one-to-one texel correspondence across chart boundaries. This
mapping permits any computation on the mesh surface which is typically carried out on a regular grid, and
prevents seams by ensuring resolution continuity along the boundary. These features are also useful for traditional
texture applications such as surface painting where continuity is important. Distortion is comparable to other
parameterization schemes, and the rectangular charts yield efficient packing into a texture atlas. We apply this
parameterization to texture synthesis, fluid simulation, mesh processing and storage, and locating geodesics.
