[vtkusers] vtk in terrain visualization

[Fei Xiong]

Hi, all

   I am now working with vtk in terrain visualization.
Suppose that my data are evenly distributed on the
joints of an unstructured grid, and the scalar data
act as elevations. How can I build the trianglation
and then render it? I have searched the FAQ package
for indication or source code, but get no obvious
answer. Can anybody give me a sample about this? Maybe
 it is not difficult for me to get some help here:)
Moreover, if there are also some wheather phenomena,
e.g. fog or cloud, to be portrayed over the landscape,
what kind of classes shall i pay attention to? Is it
difficult to create animation using vtk?

your kindness and help are cordially appreciated.

best regards
xiong fei
