Hi there,
  I was wondering if I put a height field as my ground, can I randomize
the placement of objects such as plants with relative elevation to the
HF?

I'm using povray 3.1 for linux...

Thanks,
  Simon

AFAIK, not with 3.1. You need trace which requires either megapov or 3.5.

On the other hand, if you use leveller, you have the option to export a series
of points on the surface iirc.

Doesn't anyone feel it's time to port the latest povrays to linux? ;)

I'll work my way around manually...  Thanks anyway!

Why not give megapov a try?

I might be able to help via leveller - if you send me your scene file and the hf
image I could generate some points for you.

I assume Simon's after 3.5 (since he needs trace) - are 3.5 RC's avail. for
Linux? (I can't see 'em).

Indeed!  But I had a look in the download section before where it's
not.  But I could find the link to linux povray version 3.5.

  Thanks Warp!

PS: does the 3.5 has the isofunctions?

Yes - although the syntax is slightly different than for megapov. It's still
RC (release candidate), so there is an expiry date (but you probably knew
that).

Have you tried Terraform?
It's a open source landscape/heightfield editor which runs under Linux. It
has the ability to place objects on landscapes and renders its output with
Pov-Ray 3.1

I managed to get it running under Mandrake 7.1 (after installing lots of
extra packages). Looking at the website I noticed that a new version has
appeared (version 0.9.0) which mentions "improved object placement".

See the following link for more details:
http://terraform.sourceforge.net
