Imitative Visualization

The development of illustrative and investigative visualization systems paved the way to the development of visualization systems that focus on creating realism through visualization. Such virtual realism could be exhibited in visualizing the structures or in visualizing the functions through simulation and modeling. These visualization techniques belong to two classes of fifth generation systems.

which deal with large volumetric images. Visualization techniques that are needed for biomedical modeling and simulation applications should be compatible with finite-element [49-51] and fluid dynamics techniques [52]. This will enable researchers to build rapid prototypes of the models for quick visual validation and determine some parameters of the model [53]. Also, this approach can enable them to build the model using actual geometry rather than the simplified representation the earlier modeling techniques preferred.
