Just noticed - inside Calc Temp Topology, connect Max Nb Triangles to the Max Repeat of the While node. I must have been using the frame number to step through and debug as it added a polygon at a time.

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: https://dl.dropboxusercontent.com/u/7703976/Gift%20Wrap%20No%20Coplanar.1.1.xsicompound As the name suggests, it doesn't handle coplanar points. I think that's going to need Delaunay triangulation to be fully bulletproof. gray From: softimage-boun...@listproc.autodesk.com<mailto:softimage-boun...@listproc.autodesk.com> [mailto:softimage-boun...@listproc.autodesk.com] On Behalf Of Tim Bolland Sent: Thursday, August 08, 2013 11:38 AM To: softimage@listproc.autodesk.com<mailto:softimage@listproc.autodesk.com> 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'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. Regards, Tim
