Current projects of Offshore Structures require virtual prototyping of huge CAD models. These models usually have hundreds of millions of triangles and for this reason they cannot be sent directly to current graphical boards that can render interactively only a few millions of triangles. There are many different approaches to deal with this problem including a new impostor strategy based on Voxel visualization. This strategy is promising because it deals well with level of detail, occlusion and out of core model storage. This dissertation presents a variant of the Far Voxels algorithm. This variant is implemented and tested against typical CAD models. Finally, from these tests, the dissertation presents some conclusions and suggestions for future work.
