I've posted a scene file and the corresponding 'design' file on 
povray.binaries.scene-files.
The 'design' file contains the pattern embossed on the different surfaces. 
You could simplify this down to a single colour if you want. If you want a 
different pattern on each of the 3 polyhedrons you can use 3 copies of the 
file and include the appropriate file before each 'Labeller' call. You can 
apply a different normal to each of the 3 objects too. To get waves that 
dampen with height you may want to define a normal_map for the sides of the 
tent.

To use this object in a scene you're likely to have to scale it up a fair 
bit. At the moment the object goes from y=0 to y=0.023, with a base centred 
at the origin. I'd guess you'll probably have to scale it by about 140 if 
you're working to a scale of 1 unit = 1 metre.

Chris B.
