I'm testing render a mountain and trees with media.

Trees are spheroids. Using dome light. landscape is sculpted using sculptris.

Looking good. However, even better would be to (1) randomise the tracing 
a bit creating clearings and clumps, and (2) randomise the sizes 
allowing for larger and smaller trees.

Wrote a file to place object and avoid overlap.

If you want to make a forest, then, avoiding overlap is not than 
important. You only want to prevent to much of an overlap.

Basically I store the position on a file. And apply a bit large tree model.

At this stage, I think the following might be of interest to you:

I have used code snippets tailored to my needs ever since Kirk Andrews 
posted this.

Interesting.
There once was an include file for realistic sky/(fog?) based on media 
that had proper absortion depending on the suns angle. Can't find it :(

Regarding tree placement, it would be nice if we could use voronoi 
(crackle) some howe to determine how big the crown of a tree can be before 
intersecting with the surrounding ones.  
The centre of the cell would be the trunk. The size of the cell the crown 
and the height of the tree.
