I'm planning to use this planet for a representation of "le petit 
prince" which is a character of Saint Exupery a french writer.

The planet is an isosurface, and grass a bunch of some 300000 cones.

Looks GREAT. I've had the same idea for a picture but never got lucky. The
water could be improved, I think, but the grass is great (something I hadn't
thought of) and the light is pretty, too.

Really good.. hmm.. Perhaps the stars...hmm, naa.. You know, there are too
few compared to the real universe but the grass is off-scale too.. :o)

Regards,
Hugo

This is great! It looks more like hair or fur rather than grass.  But it
-does- look like grass, too!  Say, how did you attach all that grass to the
surface anyhow?  I presume you used trace(), but I'm awfully curious how to
get it to conform to a sphere...

With tiny trees instead of grass, it will really look like a small planet!

I first thought that having a uniform random repartition of points on a 
sphere was going to be difficult but I finally found an easy solution.
I take 3 random angles and I rotate my point around all 3 axes with 
these angles.

     #local a1=360*rand(MySeed);
     #local a2=360*rand(MySeed);
     #local a3=360*rand(MySeed);
     #local InitPos = vrotate (<10,0,0>, <a1,a2,a3>);
     #local Pos=trace (Terrain, 0, InitPos, Norm);

Then, I check if the altitude is above water level and I create the 
grass blade.

There might be more optimized solutions, but this one works.

Yes, with little imagination (and more texturing), the cones could be 
taken for pine trees. But I'm thinking about adding a few trees on the 
planet and some clouds too.

Yes, you just provided me with the best image I could find on the net of 
Le petit prince. Thanks !
I think I'll have troubles modelling it ... I need to win the IRTC this 
round to get Poser. :-)
So go and vote for me (it's the whatstha.jpg image).  8-p

-And some volcanos? And a rose? Baobabs?
Or, the planet with the lamp-post could look cool; especially if it provided
it's own lighting.

-Luke.
