Group Representation of Global Intrinsic Symmetries
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Global intrinsic symmetry detection of 3D shapes has received considerable attentions in recent years. However, unlike extrinsic symmetry that can be represented compactly as a combination of an orthogonal matrix and a ...
Modeling, Evaluation and Optimization of Interlocking Shell Pieces
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
While the 3D printing technology has become increasingly popular in recent years, it suffers from two critical limitations: expensive printing material and long printing time. An effective solution is to hollow the 3D model ...
Rib-reinforced Shell Structure
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Shell structures are extensively used in engineering due to their efficient load-carrying capacity relative to material volume. However, large-span shells require additional supporting structures to strengthen fragile ...
Data-Driven Sparse Priors of 3D Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present a sparse optimization framework for extracting sparse shape priors from a collection of 3D models. Shape priors are defined as point-set neighborhoods sampled from shape surfaces which convey important information ...
Regression-Based Landmark Detection on Dynamic Human Models
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Detecting anatomical landmarks on various human models with dynamic poses remains an important and challenging problem in computer graphics research. We present a novel framework that consists of two-level regressors for ...
Semi-Automatic Conversion of 3D Shape into Flat-Foldable Polygonal Model
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
This paper presents a method that can convert a given 3D mesh into a flat-foldable model consisting of rigid panels. A previous work proposed a method to assist manual design of a single component of such flat-foldable ...
Spatial Matching of Animated Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
This paper presents a new technique which makes use of deformation and motion properties between animated meshes for finding their spatial correspondences. Given a pair of animated meshes exhibiting a semantically similar ...
An Interactive Design System of Free-Formed Bamboo-Copters
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present an interactive design system for designing free-formed bamboo-copters, where novices can easily design freeformed, even asymmetric bamboo-copters that successfully fly. The designed bamboo-copters can be fabricated ...
Retargeting 3D Objects and Scenes with a General Framework
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
In this paper, we introduce an interactive method suitable for retargeting both 3D objects and scenes. Initially, the input object or scene is decomposed into a collection of constituent components enclosed by corresponding ...
An Eulerian Approach for Constructing a Map Between Surfaces With Different Topologies
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
3D objects of the same kind often have different topologies, and finding correspondence between them is important for operations such as morphing, attribute transfer, and shape matching. This paper presents a novel method ...
