Fdsca Posted June 18, 2012 Share Posted June 18, 2012 I have a closed shape (lets say the outline of the letter T) and I want to build a curve inside that runs right down the middle. I believe its called a straight skeleton (wiki article). I was wondering if anyone has figured out a quick way to find this in Houdini. 1 Quote Link to comment Share on other sites More sharing options...
Jonatan Nordenstam Posted January 14, 2014 Share Posted January 14, 2014 Hi! I am looking into this myself and it seems like there is now quick solution for this...You may have looked at this topic: http://forums.odforce.net/topic/14151-roof-generator/?hl=%20straight%20%20skeleton There is not much information about the straight skeleton:. "Well, it's just some foreach and other sop's, some expressions,plus allot of mind bending to get them to do what it needs to be done.To be honest this thing made me think "Hey, I'm struggling to do this here in Houdini,using some nodes that are not necessarily made for this (or are they?).I should learn a little programming (Python for example).By the way, this is a pretty good example showcasing the power of Houdini (in my humble opinion at least).Maybe I'll do a tutorial some day..." This is not much of help for me at least. I am trying to get something to work myself.I will update you if I get it to work. If you have come any closer getting a straight skeleton to wok, plz update me:) Cheers! Quote Link to comment Share on other sites More sharing options...

koen Posted January 14, 2014 Share Posted January 14, 2014 in 3d you can do some fun stuff with distance fields. Looking at the images in the first post, that is where I would start. cheers, koen Quote Link to comment Share on other sites More sharing options...
edward Posted January 16, 2014 Share Posted January 16, 2014 In H13, there's an experimental (ie. WIP) SOP related to this. Modify your $HFS/houdini/OPcustomize file in a text editor and comment out the "ophide Sop polyexpand2d" line. 2 Quote Link to comment Share on other sites More sharing options...
magneto Posted January 16, 2014 Share Posted January 16, 2014 Hey Edward, that's a great tool. Do you know if there will be a 3d version? Also how does it calculate the final plane as it seems to flatten the input shape into an arbitrary plane. Quote Link to comment Share on other sites More sharing options...
edward Posted January 16, 2014 Share Posted January 16, 2014 <shrugs> Even the 2D version is experimental. 1 Quote Link to comment Share on other sites More sharing options...
