In computational mechanics, scientific visualization provides researchers and engineers with
tools for studying numerical data. The basis of each of these tools is comprised by scientific
visualization techniques.
This thesis deals with the necessary changes to conventional scientific visualization techniques
in order to visualize the results obtained from the application of particle based methods and
mesh-less methods. This is done taking into account the large amount of data that results from
the application of these methods and the presence or absence of contour information.
Moreover, it is developed a visualization technique for representing micro-cracks and
discontinuities, which are the beginning of chains of structural failures. A mesh generation
method is selected, given its provided facilities, and it is adapted to generate point clouds for
representing volumes and surfaces.
For each proposed technique we study the advantages of the data structures used, and show
its contributions to computer graphics and to data analysis
