[vtkusers] Simple-colored polygons in vtk

[Jochen Giese]

Hallo,

In my first mail I have forgotten to set a subject, sorry, so I hope now
somebody answers to my questions.

I am a newbie, and search help. I make a visualization of acoustics in a
room, so I must make simple walls and other simple "polygon" objects, too,
which has no scalar value, but a color (maybe later texture).
What is the simplest and best way to make "polygons" with these properties?
(UnstructuredGrid or PolyData, where is the different?) If somebody give me
an example, I will be happy.
 
Thank you for helping me,
Jochen Giese
