Ternary Sparse Matrix Representation for Volumetric Mesh Subdivision and Processing on GPUs
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
In this paper, we present a novel volumetric mesh representation suited for parallel computing on modern GPU architectures. The data structure is based on a compact, ternary sparse matrix storage of boundary operators. ...
Computing Contour Trees for 2D Piecewise Polynomial Functions
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Contour trees are extensively used in scalar field analysis. The contour tree is a data structure that tracks the evolution of level set topology in a scalar field. Scalar fields are typically available as samples at ...
12DoF Interaction for Scientific Visualisation
(The Eurographics Association, 2017)
This short extended abstract investigates human-computer interactions in relation to a specific Six Degree of Freedom (6DoF) input device; described is the driver development and calibration required for a novel piece of ...
Perimeter Detection in Sketched Drawings of Polyhedral Shapes
(The Eurographics Association, 2017)
This paper describes a new "envelope" approach for detecting object perimeters in line-drawings vectorised from sketches of polyhedral objects. Existing approaches for extracting contours from digital images are unsuitable ...
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 ...
Wavejets: A Local Frequency Framework for Shape Details Amplification
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Detail enhancement is a well-studied area of 3D rendering and image processing, which has few equivalents for 3D shape processing. To enhance details, one needs an efficient analysis tool to express the local surface ...
