subproject Cutting-edge technology in the field of Computer Graphics is currently found in 3D engines for computer games. This is due to the successful combination of research conducted by universities with the traditional techniques used in the digital games sector. While this technology was first developed for computer games, it is expanding its scope of application to include other sectors which are less developed as far as realistic rendering is concerned. Virtual Reality and 3D web content are the sectors which show the greatest interest in incorporating the new technologies. Therefore the purpose of this project is twofold: to continue the research on computer games technologies carried out in the project TIC2001-2416 and to apply the new technologies to the fields of Virtual Reality and 3D web content.
