TreeGen
Overview
So what is this plug for?
TreeGen creates trees (as the name suggests) based on the
settings input by the user. Depending on the case, the result may be a low
polygon tree to fill a landscape with (works great with Q-polyclone), or a fairly
highly detailed subdivision mesh with individual polygons for leaves.
The trees always grow up in Y axis, from the center of the
modeler universe. Here's the stuff that happens:
1. TreeGen creates a disc, with size and detail defined by
the settings. This is the base of the wannabe tree.
2. The disc is beveled as many times as definded by user
(segments), with some randomness (shape variation) and inset (Segment shrink).
3. Branching occurs. This is done by beveling and rotating
the extruded polygon multiple times. Branching is repeated as many times as
specified by the user.
4, All the resulting "stumps" of the branch are beveled in
the same way as step 2. Steps 2-4 are repeated as many times as specified
by the user (iterations).
5. If no leave options are specified, the tree is done. Leaves
are created by creating a tessellated sphere at the tip of each branch. If
the user wishes to use polygons for leaves, these clusters are further subdivided,
a beveling operation is done, and finally excess polygons are killed.
That's the basics, there's of course a little more to it
as usual ;-)
For technical help (Also for ModPak users!!), there is also
a mailing
list for the PlugPak users.
