Evaluating the Curvature Analysis as a Key Feature for the Semantic Description of Architectural Elements
(The Eurographics Association, 2014)
The recent developments in the fields of photogrammetry and laser scanning, have made possible mass acquisitions of heritage artifacts with a particularly high level of geometric accuracy. A processing of the digital model ...
A Tracking Approach for the Skeletonization of Tubular Parts of 3D Shapes
(The Eurographics Association, 2013)
In this paper we propose a new simple and efficient method to characterize shapes by segmenting their elongated parts and characterizing them with their centerlines. We call it Tubular Section Tracking, because it consists ...
Ellipsoidal Cube Maps for Accurate Rendering of Planetary-Scale Terrain Data
(The Eurographics Association, 2012)
Advances in sensor technology lead to a rapidly growing number of terrain data sets with very high spatial resolution. To allow reliable visual analysis of this data, terrain data for planetary objects needs to be rendered ...
Level of Detail for Real-Time Volumetric Terrain Rendering
(The Eurographics Association, 2013)
Terrain rendering is an important component of many GIS applications and simulators. Most methods rely on heightmap-based terrain which is simple to acquire and handle, but has limited capabilities for modeling features ...
Projecting Points onto Planar Parametric Curves by Local Biarc Approximation
(The Eurographics Association, 2014)
This paper proposes a geometric iteration algorithm for computing point projection and inversion on surfaces based on local biarc approximation. The iteration begins with initial estimation of the projection of the prescribed ...
Comparative Evaluation of Feature Line Techniques for Shape Depiction
(The Eurographics Association, 2014)
This paper presents a qualitative evaluation of feature line techniques on various surfaces. We introduce the most commonly used feature lines and compare them. The techniques were analyzed with respect to the degree of ...
