Initially, studies involving the Acquisition, Modeling and Visualization of three dimensional scenes were carried out. Results obtained in this first phase were a solid modeller, and some versions of visibility algorithms. The modeller, which has been repeatedly improved, already exists as a functional version for a UNIX workstation. It has been installed with locally adapted algorithms, which permit Ray-Tracing and Animation. The generation of surfaces through "Generalized Revolution", based on interpolation curves involving some original ideas, will soon be included. The Visibility Algorithms are still a target objective within our work. Some new ideas developed by the group in this area are now being explored. The working objectives of this group are: -the acquisition and modeling of three dimensional scenes -visualization with large levei of realism In the first case, we will be handled by image processing techniques; in the second, we will explore a set of new ideas in the area of Special Architecture for Computer Graphics, using the available technology as a base, but not putting aside investigation in the domain of VLSI technology for Computer Graphics. Themes to be developed: -Solid Modelling -Surface Generation through "Generalized Revolution" -VisibilityAttribution 4.0 International License10.2312/pt.19881541
