Soft Folding
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We introduce soft folding, a new interactive method for designing and exploring thin-plate forms. A user specifies sharp and soft folds as two-dimensional(2D) curves on a flat sheet, along with the fold magnitude and ...
Non-Oriented MLS Gradient Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We introduce a new approach for defining continuous non-oriented gradient fields from discrete inputs, a fundamental stage for a variety of computer graphics applications such as surface or curve reconstruction, and image ...
ShapeGenetics: Using Genetic Algorithms for Procedural Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
In this paper, we show that genetic algorithms (GA) can be used to control the output of procedural modeling algorithms. We propose an efficient way to encode the choices that have to be made during a procedural generation ...
Design Transformations for Rule-based Procedural Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We introduce design transformations for rule-based procedural models, e.g., for buildings and plants. Given two or more procedural designs, each specified by a grammar, a design transformation combines elements of the ...
Chamber Recognition in Cave Data Sets
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Quantitative analysis of cave systems represented as 3D models is becoming more and more important in the field of cave sciences. One open question is the rigorous identification of chambers in a data set, which has a deep ...
kDet: Parallel Constant Time Collision Detection for Polygonal Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We define a novel geometric predicate and a class of objects that enables us to prove a linear bound on the number of intersecting polygon pairs for colliding 3D objects in that class. Our predicate is relevant both in ...
On Realism of Architectural Procedural Models
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
The goal of procedural modeling is to generate realistic content. The realism of this content is typically assessed by qualitatively evaluating a small number of results, or, less frequently, by conducting a user study. ...
Fast Planar Harmonic Deformations with Alternating Tangential Projections
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present a planar harmonic cage-based deformation method with local injectivity and bounded distortion guarantees, that is significantly faster than state-of-the-art methods with similar guarantees, and allows for real-time ...
GWCNN: A Metric Alignment Layer for Deep Shape Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Deep neural networks provide a promising tool for incorporating semantic information in geometry processing applications. Unlike image and video processing, however, geometry processing requires handling unstructured ...
A Parallel Approach to Compression and Decompression of Triangle Meshes using the GPU
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Most state-of-the-art compression algorithms use complex connectivity traversal and prediction schemes, which are not efficient enough for online compression of large meshes. In this paper we propose a scalable massively ...
