RESUMO

A great number of applications requires a visualization system that provides multiple visions of an animated virtual environment. A natural solution is the disposal of multiple devices of visualization around an user, in order to compose a panoramic sight of the scene. In a more elaborated arrangement , panoramic scenes of the virtual environment, acquired from different points of view, are provided simultaneously to different users. Each panoramic scene presented to the user is constituted by the composition of the images generated in each surface of visualization. Therefore, it is possible to imagine each device of visualization as being a window to a virtual environment. The use of this technology aims at to enhance the perception of human beings and to increase the degree of user`s immersion. That is reached through the quantitative increase of the supplied visual stimulatons, decurrent of the use of multiple windows. A traditional approach for the development of this kind of system is based on specialized systems, that use the dedicated hardware, responsible for the control and processing centered of all the visualization devices. This work considers a distributed architecture that provides to greater scalability, portability and flexibility to the visualization system using an heterogeneous net and graphical stations of low cost. The architecture`s proposal is to to support the development of applications that present a consistent visual result of the virtual environment. Thereunto, techniques are presented to guarantee the synchronism and the integrity between the various stations.
