Recovering 3D architectural information from dense digital models of buildings
(The Eurographics Association, 2006)
In recent years the progress of 3D scanning technologies and the consequent growing commercialization of scanners opened a large spectrum of opportunities for many professionals. In particular, architects and engineers may ...
A Message-Based Annotation System for Collaborative Design Review
(The Eurographics Association, 2006)
The paper illustrates a shared annotation mechanism developed within a collaborative virtual environment for design review. This represents one of the first prototypes being developed within the European Project IMPROVE ...
Shape Reconstruction with Uncertainty
(The Eurographics Association, 2006)
This paper presents a general Surface Reconstruction framework which encapsulates the uncertainty of the sampled data, making no assumption on the shape of the surface to be reconstructed. Starting from the input points ...
Color Palette Images Re-indexing by Self Organizing Motor Maps
(The Eurographics Association, 2006)
Palette re-ordering is a well known and very effective approach for improving the compression of color-indexed images. If the spatial distribution of the indexes in the image is smooth, greater compression ratios may be ...
A Natural and Effective Calibration of the CyberGlove
(The Eurographics Association, 2006)
This work addresses the calibration of the CyberGlove, a device which provides information about the position and attitude in space of all the components of the user hand in a haptic system for the fruition of digital 3D ...
DentroTrento: an Example of Application of Computer Graphics to the Evolution of the Archaeological Site of Tridentum
(The Eurographics Association, 2006)
This paper illustrates the DentroTrento project, commissioned by the local authority for Cultural Heritage, which has lead to the creation of an edutainment system for the visitors of an archaeological site in the town of ...
Sub-part correspondence using structure and geometry
(The Eurographics Association, 2006)
The paper describes a method for recognizing similar sub-parts of objects described by 3D polygonal meshes. The innovation of our method is the coupling of structure and geometry in the matching process. First of all, the ...
3D data segmentation using a non-parametric density estimation approach
(The Eurographics Association, 2006)
In this paper, a new segmentation approach for sets of 3D unorganized points is proposed. The method is based on a clustering procedure that separates the modes of a non-parametric multimodal density, following the mean-shift ...
A study on textures and their perceptual visual dimensions as application for flexible and effective scientific visualization
(The Eurographics Association, 2006)
The use of textures is fundamental in several areas of Computer Graphics, Computer Vision and Image Processing. In this work, we focus on their main relevant attributes, in order to define and design textures as effective ...
Use of Shader Technology for Realistic Presentation of Train Prototypes in Virtual Reality
(The Eurographics Association, 2006)
The aim of the paper is to make up a virtual showroom and work-through of a train model in order to allow railway companies showing new trains prototypes, in phase of concept, and present their new design in more exhaustive ...
