RESUMO

In the last decades, virtual reality technology has been increasingly used in many applications for the society. Particularly in the beginning of 90’s, we can observe the advent of virtual reality based in multi-projections, leading to the construction paradigm of CAVE™ like virtual reality systems. The goal of this thesis is to present the research and developments related to the construction of the first multi projection completely immersive system based on commodity computer clusters called CAVERNA Digital. The work here presented is composed by an updated panorama of the state-of-art multi-projection virtual reality technologies. The concept of commodity computer clusters for virtual reality, or specifically VRCluster is shown, as well as the taxonomy for internal organization of the VRClusters. The CAVERNA Digital multi-projection system is shown, including details of the options of uncountable subsystems, like projectors, screens, video, and interaction devices, among others. This thesis contributes with another innovation: the visualization platform, called JINX, based on the open standard X3D. Aspects related to the operation of these advanced virtual reality systems are presented, which is the case of the user interface for immersive environments called SIRIUS and the management core for immersive environments called ZEUS. Finally, various performance tests were conducted to validate the integration of the uncountable resources used in the CAVERNA Digital.
