Thanks Grahame will check this out!

Back when Softimage 2012 was in beta, I built a convex hull compound. The
actual goal was to get familiar with ICE modeling, and it was a bit of failure
since I only used two topo nodes and the rest was maths and logic.
A while back I revisited the compound to refactor it, add comments, and
generally make it presentable but I never finished. Anyway, I'm attaching what
I made so far in case it's useful. It's also here:

As the name suggests, it doesn't handle coplanar points. I think that's going
to need Delaunay triangulation to be fully bulletproof.

Subject: Re: Convex Hull in ICE
Your right, for this I would be looking to create something like this in ICE. I
had a look at Guillaume's plug-in and it works great for what I would like to
achieve but my main aim here is to learn . In fact for the first step I would
settle for making just a 2D convex hull like on Alok's blog.
Cheers,
Tim
p.s After playing around with the Guillaume's convex hull topo compound I must
say it's pretty awesome!

I imagine you're looking for "pure" ICE approaches, but for what it's worth,
Guillaume Laforge made a C++ ICE node for convex hulls and was kind enough to provide its
sourcecode as well:

Here is one for the technical guys out there. I'm currently having a play
around with making a convex hull compound in ICE, and have been looking at the
great Alok Gandhi blog as a guide (
http://alokgandhi.com/blog/2011/04/17/convex-hull-maths-can-be-fun/ ). How ever
due to my lacking knowledge in ICE array manipulation, I'm having trouble
putting it into practice.
Has anyone had a play with this sort of stuff before? I image it's the kind of
exercise that would prove useful for learning.

Tim
