MessageCheers for that Graham, I had a good look at Helge's plugin, but there
are no
presets available yet and after a few hours punching in commands and getting
nothing I really expected, I figure it'll take me the best part of my life to
work out if I don't have some sort of a preset I can work from...
I'll have another mooch round and try to find something I can addapt to Helge's
plugin.
Thanks for the advice Graham, much appreciated,
Jamie McDonnell

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
