Braids with ICE

[Szabolcs Matefy]

Hey guys,

 

I’m thinking on creating braids with ICE modeling…does anybody have any idea how to do this? Just experimenting…

 

 

 

Cheers,

Does it all have to be done with a single cloud/operator?

It's much easier to accomplish by breaking into phases:
1-Generate knot curves using particle sim
2-Extrude along curves

Hello list,

I have a city generated by Cityengine (exported as obj), and some of the houses are exported with double edges.
2 houses exported on top of each other(now merged because the exported meshe was fully polygon disconnected).

I'm looking for a simple way to remove the double polygons. I tried the classic filter edges/poly/vertex, but with no luck.

Any idea ? Ice maybe ?

Thanks :)

It is maybe possible using ICE Modeling. Can you send me a mesh to test ?

Bise,

Guillaume

[olivier jeannel]

Sure !
Here's something crapy ;)

Try to apply this compound : http://dl.dropbox.com/u/5533643/Softimage/Compounds/Delete%20Double%20Edges.xsicompound

It worked for me with the crappy mode you just sent :)

[Guillaume Laforge]

I noticed some missing double edges on the base of the model, so just in case, apply the compound twice (plug it in two execute ports of the ICETree node)

I wouldn’t trust that plugin.

 

The reason it doesn’t weld is because you have coincident polygons all over place (two polygons in exactly the same place sharing the same vertices).  That’s why you see the bold highlighted edges.

 

Delete the coincident polygons and your regular filter tools should work as expected.

Hey Matt :)

Yes, and I don't trust it either ! The coincident polygons are my fault. The city is generated via data grabbed from openstreet map. But the city was 2 big, so I had to grab it in 2 half parts. The joining parts is where the mess happen. Selecting an deleting them in Cityengine is a pain, I thought I could easily filter those in SI, but I was wrong. Selecting them by hand in SI is super tricky as well...

I'm going to try Gillaume's solution, I 'll let you know.

Thanks a ton Guillaume !
Works super and fast !

Thanks guys, meanwhile I created my very first ICE modeling compound…J I modified the compound in the ICE modeling samples (columns from strands) and it works like charm. However, when I use the Deform by Curve Compound, sometimes I get stray vertices wondering around in the scene…
