Practical Fabrication of Discrete Chebyshev Nets
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
We propose a computational and practical technique to allow home users to fabricate discrete Chebyshev nets for various 3D models. The success of our method relies on two key components. The first one is a novel and simple ...
Memory-Efficient Bijective Parameterizations of Very-Large-Scale Models
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
As high-precision 3D scanners become more and more widespread, it is easy to obtain very-large-scale meshes containing at least millions of vertices. However, processing these very-large-scale meshes is still a very ...
Real-time Denoising Using BRDF Pre-integration Factorization
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Path tracing has been used for real-time renderings, thanks to the powerful GPU device. Unfortunately, path tracing produces noisy rendered results, thus, filtering or denoising is often applied as a post-process to remove ...
Learning Part Generation and Assembly for Sketching Man‐Made Objects
(© 2021 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2021)
Modeling 3D objects on existing software usually requires a heavy amount of interactions, especially for users who lack basic knowledge of 3D geometry. Sketch‐based modeling is a solution to ease the modelling procedure ...
Interactive Editing of Discrete Chebyshev Nets
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We propose an interactive method to edit a discrete Chebyshev net, which is a quad mesh with edges of the same length. To ensure that the edited mesh is always a discrete Chebyshev net, the maximum difference of all edge ...
Large-Scale Worst-Case Topology Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We propose a novel topology optimization method to efficiently minimize the maximum compliance for a high-resolution model bearing uncertain external loads. Central to this approach is a modified power method that can ...
Constrained Remeshing Using Evolutionary Vertex Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We propose a simple yet effective method to perform surface remeshing with hard constraints, such as bounding approximation errors and ensuring Delaunay conditions. The remeshing is formulated as a constrained optimization ...
Precise High-order Meshing of 2D Domains with Rational Bézier Curves
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
We propose a novel method to generate a high-order triangular mesh for an input 2D domain with two key characteristics: (1) the mesh precisely conforms to a set of input piecewise rational domain curves, and (2) the geometric ...
