General Planar Quadrilateral Mesh Design Using Conjugate Direction Field - Picture

General Planar Quadrilateral Mesh Design Using Conjugate Direction Field


We present a novel method to approximate a freeform shape with a planar quadrilateral (PQ) mesh for modeling architectural structure.

Connectivity Editing for Quadrilateral Meshes


We propose new connectivity editing operations for quadrilateral meshes with the unique ability to explicitly control the location, orientation, type, and number of irregular vertices in an input mesh while preserving sharp edges.

Simple Quad Domains for Field Aligned Mesh Parametrization - Picture

Simple Quad Domains for Field Aligned Mesh Parametrization


We present a method for the global parametrization of meshes that preserves alignment to a cross field in input while obtaining a parametric domain made of few coarse axis-aligned rectangular patches. The method is based on the topological simplification of the cross field in input, followed by global smoothing.

Boundary Aligned Smooth 3D Cross-Frame Field - Picture

Boundary Aligned Smooth 3D Cross-Frame Field


We present a method for constructing a 3D cross-frame field, and a 3D extension of the cross-frame field on surfaces (equivalent to a 4-Way Rotational-Symmetry vector field) as used in applications such as quadrangulation and texture synthesis.
