This work describes the development of a software structure that currently controls the CAVE at LNCC, as well as its use for biological data visualization. This work also includes the adaptation and configuration of the InstantReality framework considering all particularities of the CAVE built at LNCC, which amongst other things does not have square walls all around (two walls have a particular shape). In order to accompish this task we make use of the emerging X3D technology. This work also proposes a process for fast development of biological data visualization. Such process has been used to develop a series of sample applications, which included geometric description of parts of the human cardiovascular system as well as other structures such as parts of worms and other creatures, visualization of proteine models and virus envelops both relying or not on some programming language. This work also introduces important aspects of complex surface visualization and describes the implementation of a GPU based ilumination model. Additionally, some justifications are presented regarding the use of Virtual Reality as a tool for bioinformatics visuzalization or biologic applications. Finally, this work evaluates the CAVE prototype, considering each of its components, in the light of the results achieved in the biologic visualization applications developed. Problems are identified and further improvements are proposed.
