Tree3D_3.1
Purpose:
Displays a 3D Tree constructed with a simple algorithm.
Allow simple real-time variation and exploration of the generation
parameters.
Algorithm:
All branch-points (where subranches sprout from branches) are controled
by the same set of parameters, which control the number of subbranches,
the angle each subbranch makes with the extension of the branch, the
twist of the branch, and how much smaller the subbranches are from
their parents.
Randomness may be introduced in all parameters. Again, the algorithm hasn't
been optimized too much.
Revisions:
Tree3D_3.0: 5/15/93 -- first release (to sonata)
Tree3D_3.1: 5/22/93 -- adds missing files (Branch.h,m, ForestCamera.h)
-- obsoletes Tree3D_3.0
Requirements:
NextStep 3.0, with 3DKit
Optimized and debugged on a '040 ColorStation. (It's seen nothing else.)
This was a simple hack which I did to get into the 3DKit, and it turned out
good enough to share (even though it still has a few bugs). It took about 40
hours, and I have no more time to play with it. Please feel free to do what you
want with it. Also I'd like to hear from you about neat modifications you've
done.
Enjoy,

Also included are sources for the objects used:
ForestCamera.m
Displays 1 (or someday more) 3-D trees in 2-D view.
Branch
a component of a tree
renders as a cylender
Tree
a collection of branches
contains the generation parameters for the tree
My list of possible enhancements include:
Leafs
Colors
Lighting
Multiple Trees
A more sophisticated algorithm which prevents branches from collideing
