Procedural Topo Pack

[iamVFX]

A set of nodes which I made to reduce frustrations of context conversions and do perfomance critical job.

No stupid names or colors were chosen. No repeat or while nodes were used. Fully compatible with Softimage 2012.

Thank you very much, a very useful set of nodes!

[Pancho]

Thanks for sharing!

Just a quick question as it seems that you are deeply involved into this subject.

Is there a way to triple subdivide a whole mesh? Instead of subdividing each polygon into 4 new polygons, have nine of them? So each edge would be divided into three "subedges"?

Thanks so far!

cool! big thanks!

Very nice! Thanks a lot for sharing!

I'm not figure out how to do so procedurally yet. And I will probably won't, it's not the topic I'm interested in. You *could* disconnect edges and dice polygons how much you want, but you have to use standard weld operator then, since ICE one is a garbage, it accepts only one pair of vertices at once and since I'm not using repeat nodes anymore I can't do anything here. You can also use EdgeIsHard attribute, but it will cause crash on Softimage 2012.

Today I will show some cool examples with use of these nodes, many of them accept per polygon data so you can do stuff that was not possible before

Here's a clever approach by Julian Johnson (without repeat node)

Thanks for pointing that out, Cesar! Indeed, it's simpler to rebuild the whole mesh than use some of the standard ICE topology nodes.

So the answer to Pancho's question is: find people who's way smarter than me and use their compounds

Many thanks. Stuff that should been there from start.

Thanks Constantine for the topo pack.

[iamVFX]

Stop thanking me, everybody, show the pictures and ask questions

[Bullit]

Maybe a dumb question , but what is the true node there, i don't remind it.

It's just a limitation of old version, I fixed that already. If you left Clamp parameters at False value all the polygons would scaled and transform. Bu they're not now.



Also Extrude Islands returns proper Top and Side clusters now, please redownload the topo pack and test it if you have a chance

I think i am too green in ICE for this, i thought node "to per point" was to change for example context from polygons to per point but i was unable to do it.
