What object should I use to model a hill?
I have contours for this hill, and want to create a 3D view with some
proposed buildings on it.  There needs to be some earthworks to make a
platform, so the hill object will need to have a platform cut into it.

Any tips would be most appreciated.

TIA

Peter

Height field most probably, or isosurface. However, you will have to process
your contours to coloured bands (light for higher parts; dark for lower
parts). You can do this in any painting program. Make sure you
smooth/blur/blend the limits between colours. Then you can use this image in
a height_field, but also with an isosurface, as a pigment function.
Earthworks/platform can also be made on the image in a paint program.
However, if you have a height field generator like Leveller for instance,
that would even be easier to make.
You can place objects with the trace() function of POV;

Hope this helps,

Thomas

Hi Peter,

It depends on the format you've got the contours in.
If it's as an image file, then I think the method Thomas described would be 
the way to go.
If you mean that you have a series of coordinates representing the contours, 
then you'd probably be best using them to build a mesh object.

Regards,
Chris B.

Ah yes, that is right. Another possible option would then be to make a
greyscale image using Surfer for instance, but that is another matter...
