Thank you, that's what I thought too! ;-)

I think there were something around 2600-something spheres, but I
didn't take track of how long it took to generate the places. Not too
long though, a few minutes (under ten). It tried 150 times to add another
50 to the existing ones. While processing, a grid is used (blockmap?), in
which the positions are stored, in order to check only nearby grids for
collisions, not the entire amount of exisiting objects, but in the end,
all positions are saved into a single file, which is then read to place the
spheres/grass-patches (for that I still need to write a macro).

Thanks, the grass was actually just taken from a similiar image (without
the vegetation algorithm) a few months ago, nothing too funky. Every grass-blade
gets a texture picked from a User-Defined array. Though the amount of
textures are hard-coded (once generated, a blade would always use index
5, for example), I can easily use the grass-patches and some different textures
to vegetate a different climate. Makes it more versatile in use.

Thanks for the comments!
