Multi-resolution Morphological Representation of Terrains
(The Eurographics Association, 2006)
Mesh-based terrain representations provide accurate descriptions of a terrain, but fail in capturing its morphological structure. The morphology of a terrain is defined by its critical points and by the critical lines ...
3D Input devices integration in CAD environment
(The Eurographics Association, 2006)
Virtual Reality (VR) technologies are becoming commonly used tools in the product development process, starting from the styling review in the conceptual design phase, until to the Digital Mock-up (DMU) validation in the ...
Solutions to 3D Building Reconstruction from Photographs
(The Eurographics Association, 2006)
The 3D model reconstruction of buildings from uncalibrated photographs allows new useful Computer Graphics and Computer Vision applications. In this paper we survey some solutions proposed in literature and in commerce. ...
A Survey of Digital Mosaic Techniques
(The Eurographics Association, 2006)
Art often provides valuable hints for technological innovations especially in the field of Image Processing and Computer Graphics. In this paper we survey in an unified framework several methods to transform a raster input ...
From Skull to Face: an Improved Framework for Ethnically Faithful 3D Face Reconstruction
(The Eurographics Association, 2006)
3D imagery can be a useful tool for archaeologists and anthropologists committed to the study of ancient people, helping them to better visualize the results of their theories and findings. This paper presents a methodology ...
Hand Made 3d Modelling for the Reconstructive Study of Temple C in Selinunte : Preliminary Results
(The Eurographics Association, 2006)
This paper illustrates the preliminary results of the virtual reconstruction of temple C in Selinunte. The reconstruction was undertaken as part of the Land-Lab Project launched by the University of Lecce in 2003 for the ...
Multi-Modal Presentation of Work of Arts in Virtual Reality with Simulation of Multi-Mirror Reflection
(The Eurographics Association, 2006)
The use of different media such as photography and virtual reality combined with different presentation modalities may provide a user with an extraordinary tool for exploration and appreciation of real work of art. This ...
An Experimental Setup to Evaluate the Performance of Tone Mapping Algorithms
(The Eurographics Association, 2006)
Many algorithms have been proposed in the literature to solve the problem of mapping tones from high dynamic range sources to low dynamics displays, while preserving the information conveyed by the original scene. Methods ...
Real-time Cataract Surgery Simulation for Training
(The Eurographics Association, 2006)
Cataract is a clouding of the eye's natural lens, normally due to natural aging changes, and involving at least half of the population over 65 years. Cataract extraction is the only solution for restoring a clear vision, ...
Simulation of X-ray Attenuation on the GPU
(The Eurographics Association, 2009)
In this paper, we propose to take advantage of computer graphics hardware to achieve an accelerated simulation of X-ray transmission imaging, and we compare results with a fast and robust software-only implementation. The ...
