Re: SimulatedFrameFraction on polymesh ?

If you are into polygon Island ID, this is a must have :

Fast as hell !

Re: SimulatedFrameFraction on polymesh ?

[Olivier Jeannel]

Hey Peter ! Thank's a lot !
You're totally right ! I Will try something like this. I'm doing some fast
R, moving from one kind of "test" to another (now I'm on something else).
Playing a lot wit PolygonIslandID. Slow to generate, but super handy !
I might come back to you again with questions ;)

Thank you again !
