Hi Antimbé, > I would like to know if visad has a program which can triangulate a 3D > data, and > vizualized the result triangulation. You can triangulate 3-D data by constructing an Irregular3DSet (If it is a tetrahedralization), or an Irregular2DSet (if it is a triangulation embedded in 3-D), which will implicitly invoke one of the system's Delaunay algorithms (it includes both Watson's and Clarkson's). If it is a embedded triangulation, you can visualize with a program similar to visad/examples/Test62.java. If it is a tetrahedralization, you'll need to use the topology from the Delaunay class to construct a VisADTriangleArray that you visualize with a RealType mapped to Display.Shape. Note that VisAD is a library so requires some programming. The classes I mentioned are described in the Developer's Guide and used in various examples.
