Hi Alan,
I´ve been playing a bit more with the syflex 3.0 cloth.
http://www.hafenlola.com/downloads/Leydecker_reduced.jpg
After trying various types of tesselation I mostly end
up using my allready existing basemesh, extracting the
area I need and adding 1-2 local subdivisionsteps.
Using two pinconstraints (the cubes) and the default
syflex settings plus one collisionmesh (the arm here)
is then solved in almost realtime.
Once there is a nice look, I copy the syflexclothmesh,
freeze it at the current frame and simply add a polygon
reduction, playing with the settings mostly creates a
good start for a reasonably simple mesh.
In this case I´ll take the lower mesh and refine the
edgeloops to fit both the body while keeping the volume.
A topology brush would be marvelous...
Thanks for getting me on the way guys,
Cheers
tim

Unfortunately the only option I've found for delauny tesselation so far is
when you're converting a curve to mesh.
If you go to the tesselation page and change the type to delauny. Then set
the maximum area you'll get a mesh that simulates nicely.
Though we don't have anyway to retesselate a polymesh/subdivided polymesh
with delauny - which would be exceptionally useful for cloth sim.
Cheers,
Alan.

No problem. It´s been rewarding to figure
it out myself and play with the results.
But how do you get delauny tesselation?
Is this something compareable to the way
Maya Cloth garments/meshes are tesselated?
I can´t work on this thing more now, need
to get other things done instead but will
see if I can come up with something similar
to the syflex solve using the Foundation Cloth,
my adv expires in September, will probably
just go for a Foundation or maybe an Essential
to have access to satellite rendering.
Whatever, thanks for the tips!
Cheers
tim

Hi Tim,
Yeah - I found by adding a quadrangulate on top and subdividing you get
really nice results - with much faster solves.
Sorry I didn't mention that before.
Cheers,
Alan.
