Towards the Creation of Digital Stones from 2D Samples
(The Eurographics Association, 2014)
In order to decide which preservation strategies one should follow for Cultural Heritage objects made of stone, it is necessary to estimate the impact of different alternative strategies. A useful aid in such a process is ...
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 ...
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 ...
