Layout and Parameterization
Bounded-Distortion-Mapping Spaces For Triangular Meshes
This paper introduces generic convex spaces of bounded-distortion, piecewise, linear mappings of triangular meshes. It shows how common geometric-processing objective functionals can be restricted to these new spaces, rather than to the entire space of piecewise linear mappings, to provide a bounded-distortion version of popular algorithms.

Global Parameterization by Incremental Flattening
A global parametrization flattens a surface to a plane for texture mapping, generating geometry images, or quadrangulating. This paper describes an iterative flattening procedure that concentrates curvatures at isolated singularities (corresponding to quadrangulation vertices with valence different from 4) to generate a parametrization with far lower distortion than previous techniques.

Dual Loops Meshing: Quality Quad Layouts on Manifolds
A theoretical framework and practical method for automatic construction of simple, all-quadrilateral patch layouts on manifold surfaces. The resulting layouts are topologically coarse and have a high geometric fidelity, so they are ideally suited for surface parameterization or for generation of structured quad meshes.

Fields on Symmetric Surfaces
An algorithm for designing smooth N-symmetry fields on surfaces, respecting generalized symmetries of the shape while maintaining alignment with local features. This formulation is based on global generalized symmetries with no isometry assumptions. The apper also presents an algorithm for computing symmetry maps for surfaces of genus zero.
