Back
I was thinking of making a scop for something similar sometime instead
of a one off script, but I'm UV and instance hell right now. if I was to
tackle this, not being at a level yet to make an Lsys and construct the
mesh, I think I'd just make a split and iterations rule system and use
XSI built in OPs at each step.
Or I think you could get Helges Lsys script to make some paths for mesh
extrusions.
Converting a plugin requires understanding the process/concepts they
use, like the links you guys sent me yesterday on UVpelting.
Perhaps do a search on L-systems. I have a few lsys links in my own
resources.
Take a look at Helges approach, the use of an annotation property as a
place to store rules as presets is a very good idea as well as others he
uses in it.

Hay Graham,
any chance you could have a quick look at porting this little lightwave
doodaa
over to a plugin for XSi, or give me a crash course in how to do it
myself?
http://perso.wanadoo.fr/dpont/plugins/TreeCage_Lscript.htm#Manual
It'd be a usefull plugin to have! And I'd love to know the process of
converting a plugin like this...
Cheers Graham (or Helge if he can help!)
Jamie

the few XSI tools I'm aware of are
-a very cool twig addon posted a way back, by Vincent Fortin.
-Helge has an L-system OP look on his site.
-and I think there are a few based generation or other methods floating
around somewhere that uses standard XSI OPs such as extrude etc with
rules for branching.
then of course there are lots of external tools/apps for generating
branch forms and trees etc. I use ho-- ---- -- for this for the
animatable params and rules then put sequential geo or the branch paths
back into xsi.
'The Algorythmic beauty of plants' book will help with the formulas for
lsystems.

Hi list...
Has anyone had to tackle the making of meshes using procedural fractals
for branches on trees etc?
I need to create the vein structure inside a lung, they are made up very
similar to the structure of a tree...
any ideas? Helge?
Tar the noooo
