A Subspace Method for Fast Locally Injective Harmonic Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a fast algorithm for low-distortion locally injective harmonic mappings of genus 0 triangle meshes with and without cone singularities. The algorithm consists of two portions, a linear subspace analysis and ...
Polycube Shape Space
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
There are many methods proposed for generating polycube polyhedrons, but it lacks the study about the possibility of generating polycube polyhedrons. In this paper, we prove a theorem for characterizing the necessary ...
Exact Constraint Satisfaction for Truly Seamless Parametrization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
In the field of global surface parametrization a recent focus has been on so-called seamless parametrization. This term refers to parametrization approaches which, while using an atlas of charts to enable the handling of ...
Compacting Voxelized Polyhedra via Tree Stacking
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Volume compaction is a geometric problem that aims to reduce the volume of a polyhedron via shape transform. Compactable structures are easier to transport and in some cases easier to manufacture, therefore, they are ...
On Evaluating Consensus in RANSAC Surface Registration
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Random Sample Consensus is a powerful paradigm that was successfully applied in various contexts, including Location Determination Problem, fundamental matrix estimation and global 3D surface registration, where many ...
Local Editing of Procedural Models
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Procedural modeling is used across many industries for rapid 3D content creation. However, professional procedural tools often lack artistic control, requiring manual edits on baked results, diminishing the advantages of ...
Subdivision Schemes for Quadrilateral Meshes with the Least Polar Artifact in Extraordinary Regions
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
This paper presents subdivision schemes with subdivision stencils near an extraordinary vertex that are free from or with substantially reduced polar artifact in extraordinary regions while maintaining the best possible ...
Dual Sheet Meshing: An Interactive Approach to Robust Hexahedralization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
The combinatorial dual of a hex mesh induces a collection of mutually intersecting surfaces (dual sheets). Inspired by Campen et al.'s work on quad meshing [CBK12,CK14], we propose to directly generate such dual sheets so ...
Surface Fairing towards Regular Principal Curvature Line Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Freeform surfaces whose principal curvature line network is regularly distributed, are essential to many real applications like CAD modeling, architecture design, and industrial fabrication. However, most designed surfaces ...
