Robust Polylines Tracing for N-symmetry Direction Field on Triangulated Surfaces

This paper proposes an algorithm for tracing polylines that are oriented by a direction field defined on a triangle mesh. The challenge is to ensure that two such polylines cannot cross or merge. This property is fundamental for such applications as mesh segmentation and was impossible to enforce with existing algorithms.

Frame Fields: Anisotropic and Non-Orthogonal Cross Fields

Introducing frame fields, a non-orthogonal and non-unit-length generalization of cross fields. This paper generalizes existing quadrangulation algorithms to generate anisotropic and non-uniform quad meshes whose element shapes match the frame field.

Robust Field-Aligned Global Parametrization

This paper describes a robust algorithm for global field-aligned parametrizaiton of meshes. The algorithm ensures local bijectivty of the result for any input mesh and field, possibly at the expense of inserting a small number of additional cones.

Exploring Quadrangulations

With a framework for exploring topologically unique quadrangulations of an input shape, this paper shows applications of shape-space exploration, remeshing, and design to underline the importance of topology exploration.

Weighted Triangulations for Geometry Processing

This paper introduces a new notion of discrete metric that characterizes the construction of primal-dual structures on arbitrary triangulations and thus augments the discretization of surfaces for digital geometry processing.
