RE: Assigning attributes to polygon islands using ICE

2012-06-07 Thread Thomas Volkmann
I can really recommend Guillaumes addon. As Jens said we were using it on our
last project and it did the job perfectly. It is not fast, and you definitely
don't want to forget to freeze the model (like I did after a 2 hour
calculation), but then you can just add all sort of attributes for usage in the
rendertree.

cheers,
Thomas

Hand modelled chunks unfortunately... it's actually stained glass pieces.  I'm 
probably just going to create my own color texture for now due to time 
constraints but I would like to have a more procedural approach in the future.

How are you fracturing the mesh? IIRC Momentum and ImplosiaFX both provide 
polygon island IDs.

Re: Assigning attributes to polygon islands using ICE

2012-06-06 Thread Jens Lindgren
I would love to know if there is another, faster way to do it now.
We used your compunds on our latest project and it took almost 2 hours
every time we recalculated the island attributes so we tried not to do
that very often.
We also did the calculation half way through the modeling process, adding
chamfers and final detail after we froze the mesh, so yes, freeze is
definitely your friend here.

It is an old addon and there is maybe a better way to find all those
islands now (as we've got more polygon mesh attributes since 2012).
If you are using it to define the islands instead of using a script, you
should freeze the ICE Tree once done, as it can be very slow (it was using
several repeat nodes if I remember correctly).

Cheers,

Guillaume Laforge

Is this feasible?  I'm trying to assign random color values to points based on 
their connectivity i.e. fractured mesh where each chunk has a random value or 
color.  The mesh isn't light so I'm wondering if this is going to be a slow 
process or if it's even possible.

I don't see why it wouldn't be possible.

I had a thread a couple of years back where an ID from Island compound was
shared.. not sure if it was public on the list.

Worst case, you could get island ID's from a script, then populate an
attribute that way.
