Procedural Topo PackAuthor: Constantine Tarasenkov
Updated Feb 2013 Various ICE topology compounds that I made for last months. Fully compatible with SI 2012. After installation they can be found in Context, Interactive and Topology categories of the Tool tab menu.

Contents: Build Array from Set Node (for Softimage 2012), Array to Edge Set, Array to Polygon Set, Array to Sample Set, Array to Vertex Set, Build Array per Edge, Build Array per Point, Build Array per Polygon, Build Array per Sample, Delete Topology, Disconnect Islands, Get Edge Position, Set Edge Position, Get Polygon Position, Set Polygon Position, Polygon Index to CAV, Vertex Index to CAV, Select Polygons Interactive, Slice to Pieces, To per Edge, To per Point, To per Polygon, To per Sample

The recent updates from the si-community thread linked below include: Greeble, Slice on Cubes, Extract Polygon Island, Split Edge Equally

This looks very nice, could you do it just partially?

:D haha! curious about the bunny inside the bunny did you made it on propose? Did you extruded polygon islands?

Does it needs Momentum?

No, you should remember that is not a boolean operation, the inner bunny generated automatically by the inverse extrusion, you can check how it works in a compound

Of course not, you can use it for other types of effects, if you find any :D It's so useless, I'm currently trying to figure out why did I spend so much time on this. Anyone tried Grasshopper?

I don't think it is useless, besides we never know what effect someone want. For example sucessive effects, a sort of matrioska of falling cubes...


Can you show the icetree of this one at top of this page:

Slice on Cubes.xsicompound broke clusters information

It breaks cluster information, it breaks uv and custom normal maps because sometimes topology operations shuffles component index order in a chaotic and unpredictable manner

Hi Constantine,

is it possible to use Split Edge Evenly modulated by edgelength? (So the longer an edge is, the higher the nb of points.) I've been trying to get that to work but I'm afraid I'm too crap in ICE to figure it out. It must be something to do with context not being right (nb points is per object, edgelength is per edge element) but all my attempts at changing context have failed.

Can you (or someone else) give me some more? As in: I still can't figure it out. :ymblushing:

Can you do it with repeat node?

Here's something. Roughly speaking, if EdgeLength = X, then it splits that edge into X edges. You should be able to generalize that and then use a Repeat node to apply to all edges.

Great work, Steve! There's no need for repeat node with Oleg's trick

[ just realized how stupid it was to name my version "even" and this "equal". oh well ]
