Streamlines for Illustrative Real-Time Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Line drawing techniques are important methods to illustrate shapes. Existing feature line methods, e.g., suggestive contours, apparent ridges, or photic extremum lines, solely determine salient regions and illustrate them ...
Watertight Ray Traversal with Reduced Precision
(The Eurographics Association, 2016)
Reduced precision bounding volume hierarchies and ray traversal can significantly improve the efficiency of ray tracing through low-cost dedicated hardware. A key approach to enabling reduced precision computations during ...
Visibility Analysis in a Point Cloud Based on the Medial Axis Transform
(The Eurographics Association, 2015)
Visibility analysis is an important application of 3D GIS data. Current approaches require 3D city models that are often derived from detailed aerial point clouds. We present an approach to visibility analysis that does ...
Consistent Shape Maps via Semidefinite Programming
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Recent advances in shape matching have shown that jointly optimizing the maps among the shapes in a collection can lead to significant improvements when compared to estimating maps between pairs of shapes in isolation. ...
CoWRadar: Visual Quantification of the Circle of Willis in Stroke Patients
(The Eurographics Association, 2015)
This paper presents a method for the visual quantification of cerebral arteries, known as the Circle of Willis (CoW). The CoW is an arterial structure that is responsible for the brain's blood supply. Dysfunctions of this ...
Instant Visualization of Secondary Structures of Molecular Models
(The Eurographics Association, 2015)
Molecular Dynamics simulations are of key importance in the drug design field. Among all possible representations commonly used to inspect these simulations, Ribbons has the advantage of giving the expert a good overview ...
Curve Reconstruction with Many Fewer Samples
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We consider the problem of sampling points from a collection of smooth curves in the plane, such that the CRUST family of proximity-based reconstruction algorithms can rebuild the curves. Reconstruction requires a dense ...
Crawl through Neighbors: A Simple Curve Reconstruction Algorithm
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Given a planar point set sampled from an object boundary, the process of approximating the original shape is called curve reconstruction. In this paper, a novel non-parametric curve reconstruction algorithm based on Delaunay ...
Bijective Composite Mean Value Mappings
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We introduce the novel concept of composite barycentric mappings and give theoretical conditions under which they are guaranteed to be bijective. We then focus on mean value mappings and derive a simple procedure for ...
Adaptive Sampling for On-The-Fly Ray Casting of Particle-based Fluids
(The Eurographics Association, 2016)
We present a fast and accurate ray casting technique for unstructured and dynamic particle sets. Our technique focuses on efficient, high quality volume rendering of fluids for computer animation and scientific applications. ...
