Guided Real-Time Scanning of Indoor Objects
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Advances in 3D acquisition devices provide unprecedented opportunities for quickly scanning indoor environments. Such raw scans, however, are often noisy, incomplete, and significantly corrupted, making semantic scene ...
General Point Sampling with Adaptive Density and Correlations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Analyzing and generating sampling patterns are fundamental problems for many applications in computer graphics. Ideally, point patterns should conform to the problem at hand with spatially adaptive density and correlations. ...
Fast and Memory-Efficient Voronoi Diagram Construction on Triangle Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Geodesic based Voronoi diagrams play an important role in many applications of computer graphics. Constructing such Voronoi diagrams usually resorts to exact geodesics. However, exact geodesic computation always consumes ...
A Constrained Resampling Strategy for Mesh Improvement
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
In many geometry processing applications, it is required to improve an initial mesh in terms of multiple quality objectives. Despite the availability of several mesh generation algorithms with provable guarantees, such ...
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. ...
Overview + Detail Visualization for Ensembles of Diffusion Tensors
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
A Diffusion Tensor Imaging (DTI) group study consists of a collection of volumetric diffusion tensor datasets (i.e., an ensemble) acquired from a group of subjects. The multivariate nature of the diffusion tensor imposes ...
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 ...
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 ...
Effective Characterization of Relief Patterns
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
In this paper, we address the problem of characterizing relief patterns over surface meshes independently on the underlying shape. We propose to tackle the problem by estimating local invariant features and encoding them ...
Object Completion using k-Sparse Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a new method for the completion of partial globally-symmetric 3D objects, based on the detection of partial and approximate symmetries in the incomplete input dataset. In our approach, symmetry detection is ...
