Adaptive Tessellation of Subdivision Surfaces in OpenSG
(The Eurographics Association, 2003)
The need for realistic models especially in virtual reality environments leads us to freeform shapes like subdivision surfaces. Based on a standard polygonal mesh, the modeller can build various kinds of shapes using an ...
Incomplete 3D Shape Retrieval via Sparse Dictionary Learning
(The Eurographics Association, 2015)
How to deal with missing data is one of the recurring questions in data analysis. The handling of significant missing data is a challenge. In this paper, we are interested in the problem of 3D shape retrieval where the ...
Structure-aware Stylization of Mountainous Terrains
(The Eurographics Association, 2017)
We present a method for the stylization of mountainous terrains that allows creating abstract representations in different rendering styles. Our method consists of two major components: structure-aware terrain filtering ...
Instant Level-of-Detail
(The Eurographics Association, 2011)
Highly detailed models are commonly used in computer games and other interactive rendering applications. In this context, static levels-of-detail are frequently used to achieve real-time frame rates. While this is a simple ...
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 ...
Optimization Techniques for Approximation with Subdivision Surfaces
(The Eurographics Association, 2004)
We present a method for scattered data approximation with subdivision surfaces which actually uses the true representation of the limit surface as a linear combination of smooth basis functions associated with the control ...
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 ...
