I followed Norbert's suggestion and added the possibility to place the
objects on a landscape (just one line of code).
My next effort is something concerning the textures of the placed objects
(i.e. they could be influenced by another map, or by their position, or by
the relative position of the objects around...) but I haven't got any good
and clear idea yet.
In this example 500 spheres and 500 boxes are placed on a landscape
following a simple checker pattern.
Feedback is appreciated.
Jonathan.

Could you include re-orientation of the objects to the normal of the
landscape as an option?
Looks great!
All the best,
Andy

That's coming along nicely! In fact this does exactly what I was trying to
do with a grass macro that never went anywhere. Could you post the one line
of code? I never got the hang of the trace function.

If you want to know the y coordinate of a point (i.e. its height):
#local _alt=vdot(y,trace( land, temp_pos+10000*y,-y)); // check the
altitude
or, even easier:
#local _alt=(trace( land, temp_pos+10000*y,-y)).y; // check the altitude
(I didn't check if the last notation works, but it should).
Where land is the landscape object,
temp_pos is the coordinate (of XZ plane) you want to check (you are supposed
to not use landscapes higher than 10000 units...).
For normal calculation things are slightly more complicate (even if it's
just another line of trig formulae).

Done.
Thank you for the suggestion!

Yeah, I was thinking so too.
I'll try.

...and here's how it looks with a heightfield.
2700 spikes and no probability map this time.

Oh good lord. It *is* now a VERY COOL macro... how
about object orientation parameters, possible to add in
or not?

Why bother? I'm not interesting.
But... maybe "Ballet pour ma fille" will be.
