The Visual Computing Lab (VCLab), one of the research departments of CNR-ISTI, has been active in visualisation and computer graphics since 1984; it is now composed of 21 members. Current research focuses on geometric processing, 3D digitization/scanning, visualization systems, multi-resolution representation and rendering of huge datasets, 3D Web Applications. VCLab has a long track record in the use of 3D graphics for Cultural Heritage applications, with important collaborations with CH institutions at national and international level (museums, restoration labs, governing bodies). VCLab participated in a number of EU and national projects and has a very solid experience in the design of open source systems (e.g. MeshLab http://meshlab.sourceforge.net/ and the recent 3DHOP family of web-based visualizers http://vcg.isti.cnr.it/3dhop/).
