RESUMO

Volumetric data structures are of extreme utility in various applications, and particularly in the area of Scientific Visualization. These structures are useful in two stages of the visualization process. The first one is in data representation, that is, in the organization of information associated with the values, measured or simulated, to be visualized. The other phase of the visualization data flow that needs a data structure is the exploration phase. It would be useful to have a model designed to be used both for interactive exploration and for simulation in a number of application, for example, in virtual surgery. A volumetric data structure, named Singular Half-Face (SHF) is being developed at the ICMC, that has as its main characteristic the explicit modeling of singularities present in the model, besides other essential topological elements. This dissertation aims at testing the viability of this structure in a context of visualization in data flow, by incorporating it in the Visualization ToolKit (VTK) class library, whose data structures are extremely poor in definition of the topology of the objects that they represent. By adding SHF to this library and carrying out conventional visualization and data exploration on it, we wish to study its support to all the phases of the visualization process.
