Advances in both terrestrial laser scanning (TLS) hardware and photogrammetric solutions combined are creating increasingly more precise and rich 3D coloured data. In this article we show how Computer Graphics and Visualization techniques have played an important role in managing, modelling, and fusing data in an increasing myriad of applications such as environmental surveying, structure analy...

Image-based 3D modelling tools and techniques can be used to support some stages of the archaeological process. Two application examples, for two sites of the Roman Era, are presented, illustrating the usage and usefulness of such tools for the archaeological survey. For a quadrangular pool in the Milreu Roman Villa (Faro, Portugal), the 3D models resulting from the application of two different...

Today, communication devices are evolving towards friendly–user interactivity while permanently eyeing towards 3D display technologies. As such, 3D face generation, modelling and animation techniques are in the frontline to design realistic animated 3D talking faces. Simple, reliable and economic, 2D image processing techniques have been widely used to reconstruct 3D faces. This paper focuses o...

Modelling a three-dimensional (3D) point cloud with smooth mathematical surfaces or high-quality triangle meshes is an essential component of many applications in Computer Graphics, Visualization and Computer-Aided Design/Engineering. A vital prerequisite for that is the construction of a parameterization for a given 3D point-set; this problem is the focus of the present paper. The proposed met...

Geno3D (http://geno3d-pbil.ibcp.fr) is an automatic web server for protein molecular modelling. Starting with a query protein sequence, the server performs the homology modelling in six successive steps: (i) identify homologous proteins with known 3D structures by using PSI-BLAST; (ii) provide the user all potential templates through a very convenient user interface for target selection; (iii) ...
