Abstract
In this paper the work of the Computer Graphics & CAD group at INESC.Norte, in Solid Modelling, Surface Generation, Visibility and other 3D areas, is described. This group has created a working environment, based on a 3D kernel developed at INESC, which allowed the easy integration of other works, ranging from Solid Modelling to Surface Generation to Visibility, ect. The results achieved seem to be good enough to encourage to continue our effort, so that, in the near future, we can have a stronger and more flexible 3D kernel, good enough to be used in industrial developments and as a research starting point, for areas like Image Synthesis, 3D Graphics User Interfaces, and so on. © 1990.

COMPUTATIONAL MODELLING OF OBJECTS REPRESENTED IN IMAGES: FUNDAMENTALS, METHODS AND APPLICATIONS

Abstract
In this paper we address the problem of automatically computing a set of views over a simulated three dimensional enviromnent. The viewing system aims at, for each moment, supplying the user with the most pertinent information in order to allow a good understanding of the evolving environment. Our approach relies on an innovative optimization architecture that enables intelligent optimization techniques based on simulated annealing and genetic algorithms. Reported experiments were performed in urban rescue scenarios from the RoboCup Rescue Domain. We outline the possible extension of the proposed architecture to other visualization problems and argue on how several problems within the fields of Visualization and Rendering can benefit from it.
