Projection Mapping on Arbitrary Cubic Cell Complexes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
This work presents a new representation used as a rendering primitive of surfaces. Our representation is defined by an arbitrary cubic cell complex: a projection‐based parameterization domain for surfaces where geometry ...
Multi‐Scale Kernels Using Random Walks
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We introduce novel multi‐scale kernels using the random walk framework and derive corresponding embeddings and pairwise distances. The fractional moments of the rate of continuous time random walk (equivalently diffusion ...
Image Space Rendering of Point Clouds Using the HPR Operator
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
The hidden point removal (HPR) operator introduced by Katz et al. [KTB07] provides an elegant solution for the problem of estimating the visibility of points in point samplings of surfaces. Since the method requires computing ...
Low‐Cost Subpixel Rendering for Diverse Displays
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Subpixel rendering increases the apparent display resolution by taking into account the subpixel structure of a given display. In essence, each subpixel is addressed individually, allowing the underlying signal to be sampled ...
Modelling of Non‐Periodic Aggregates Having a Pile Structure
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
This paper presents a procedure for modelling aggregates such as piles that consist of arbitrary components. The method generates an aggregate of components that need to be accumulated, and an aggregate shape represents ...
On Perception of Semi‐Transparent Streamlines for Three‐Dimensional Flow Visualization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
One of the standard techniques to visualize three‐dimensional flow is to use geometry primitives. This solution, when opaque primitives are used, results in high levels of occlusion, especially with dense streamline seeding. ...
Time Line Cell Tracking for the Approximation of Lagrangian Coherent Structures with Subgrid Accuracy
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Lagrangian coherent structures (LCSs) have become a widespread and powerful method to describe dynamic motion patterns in time-dependent flow fields. The standard way to extract LCS is to compute height ridges in the ...
Occluder Simplification Using Planar Sections
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We present a method for extreme occluder simplification. We take a triangle soup as input, and produce a small set of polygons with closely matching occlusion properties. In contrast to methods that optimize the original ...
Boosting Techniques for Physics‐Based Vortex Detection
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Robust automated vortex detection algorithms are needed to facilitate the exploration of large‐scale turbulent fluid flow simulations. Unfortunately, robust non‐local vortex detection algorithms are computationally intractable ...
On Near Optimal Lattice Quantization of Multi‐Dimensional Data Points
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
One of the most elementary application of a lattice is the quantization of real‐valued s‐dimensional vectors into finite bit precision to make them representable by a digital computer. Most often, the simple s‐dimensional ...
