Hi.

I want to find out, how to create a cylinder where the upper round side
has the curvaceous shape of a height-field. See the height_field
attached to this posting.

PS: I use water_level 0.0001 for this height-field at the moment, to
make it round.

Use intersection{} ?

intersection {
   height_field {}
   cylinder {}
}

Then make a union of the circular height_field and the cylinder, 
translating it to the top. Use the parameter 'open' with the cylinder to 
remove the caps.

I use:
intersection{
  cylinder{Top*y, Bottom*y, Radius}
  hight_field{....}
  texture{SomeTexture}
  rotate YourDirection
  translate YourLocation
}

Just make sure that the top of the cylinder reach slightly above the 
highest point of the hight_field, and that the hight_field is scaled 
wide enough to completely cover the cylinder.
