Just a test of my vegetation algorithms, taking
special focus on the growth/spreading from
seeds...

Comments?

Looks nice and smooth.  Can it do multiple species?

Not yet, but I'm thinking about how to implement that. Shouldn't
be too difficult, just need to modify some loading scripts...

    I was going to ask that, but also, do you plan to have different species
competing for space/resources and, therefor, have vegetation die off and
repopulating available space ?

As for the question regarding multiple species,
look at the answer to David's post.

Regarding your question:
Its not actually a simulation, but a system that should be
used to position objects on a heightfield, in regard to
slope and intersections of objects. Building the system to
compete, with dying objects etc, would be very difficult
to implement I guess, and modifying the exisiting code is
no easy task (is already over 1000 lines of code pure
vegetation-macros, add some other, older macros of
name-generation, vector sorting etc...).

But I'll keep it in mind in case I change my mind...

That's a lot of code!  ;o)  If you check for collision, do you check only
neighbouring objects? How does the parse time grow, with more dense
vegetation? Does it increase unpleasantly?

    Sure, but I was thinking if you have say two or three different species
spreading from two or three different source points I think you're going to
get fairly predictable and un-natural looking patchy vegetation.
    Implement competition/die off/repopulation and you should get a more
realistic mix of vegatation across the whole heightfield.
