DBaciu 10 Posted March 14, 2013 This are the edges (hips, valleys, ridges) as geometry. Share this post Link to post Share on other sites
kgoossens 82 Posted March 14, 2013 Very nice, You could also do a straight skeleton on the ridges themselves so they don't self intersect. Share this post Link to post Share on other sites
DBaciu 10 Posted March 14, 2013 Thank you, Kim. What do you mean? They don't intersect (see image 001). There is a problem, is the intersection itself (the joint). It's a kind of mean thing (thank god it only appears at big differences in slope between joining edges. I don't know how this problem would be solved in the real life (a real construction). See the images. Share this post Link to post Share on other sites
kgoossens 82 Posted March 14, 2013 It is not these sections I'm talking about. It is what you can see in complex2.jpg when ribbon is thick it seems to intersect itself when you have strong curvature. Share this post Link to post Share on other sites
DBaciu 10 Posted March 14, 2013 I understand now, but to run the straight skeleton on those things would be utterly overkill. That thing is just a particular case caused by a too acute angle on the main (path) shape. Or to beefy of a profile. A Schwarzenegger of a profile. But it's an idea to be noted, maybe for further development. Share this post Link to post Share on other sites

But it's an idea to be noted, maybe for further development. In case of building roofs this is true. But I see this tool as being very useful as well for creating ornaments for example, where very thick ribbons could be required. I wouldn't use it to create rooftops only. Is this inspired on the work of Sven Havemann & Dieter W. Fellner Generative Modeling Language? Share this post Link to post Share on other sites
DBaciu 10 Posted March 14, 2013 1. Indeed, I used this tool to experiment modeling all kind of stuff. 2. No, it is not, but that seems very interesting. Share this post Link to post Share on other sites
DBaciu 10 Posted July 17, 2013 Hello guys, I have an update to the roof generator that I want to show you. Now it can make gabled roofs. Gables doesn't need to be on rectangular sides (90 degrees etc), they can be anywhere. Also multiple (chained) gable walls are supported. See the images. I marked with red the sides that will become gables. There are a few minor problems to be solved, though. Ps: in case you don't know, this tool has been on Orbolt since April. In case you played with it like for example Freaq wanted, maybe some comments are in order... Share this post Link to post Share on other sites
old school 624 Posted July 18, 2013 This thing is an architect's dream! Makes the roof generator in Revit look simplistic. Absolutely nutbar! Share this post Link to post Share on other sites
DBaciu 10 Posted July 18, 2013 Thank you very much! I'm honored! Share this post Link to post Share on other sites
DBaciu 10 Posted August 5, 2013 Well, I managed to turn this into a weighted solution. Now every edge can have a different angle (even negative ones, which goes outside of the contour) Share this post Link to post Share on other sites
Diego A Grimaldi 82 Posted November 20, 2013 This is insanely awesome! Congrats Did you end up making an OTL out of it? Did you publish it? Share this post Link to post Share on other sites
DBaciu 10 Posted November 24, 2013 Thank you very much! Well, if you are talking about this last post with the weighted solution then no, it is not completed for now, it needs some more work to be usable. I hope I'll be able to finish it soon. If you are talking about the whole thread then yes, an older variant of this this roof generator is on Orbolt for quite some time now Share this post Link to post Share on other sites
hyperforce 19 Posted January 28, 2014 (edited) I'm looking into creating something using reversed straight skeleton. However no-one but you seems to have found a workable method within Houdini that I can tell. Is there any chance you would write a tutorial or release your straight skeleton method. I checked your file on orbolt, but its a file that even if I were to pay 130 dollars It won't allow me to learn from it. I'd rather pay for a tutorial than for a tool I can't learn from.

DBaciu 10 Posted January 29, 2014 Hello. Lately I received a few calls from people asking me to make a tutorial or release this method in some way (maybe unlock the asset). And yes, I was (I am) thinking of making a tutorial but this will take some time. Unlocking the asset is another possibility, I'm not sure... What do you mean by "reversed straight skeleton" and what you'll be using it for (if you don't mind the question)? Share this post Link to post Share on other sites
konstantin magnus 407 Posted January 31, 2014 You can add me to the list of people being highly interested in an tutorial on creating roofs (or any type of complex real world geometry) procedurally. Share this post Link to post Share on other sites
freaq 38 Posted January 31, 2014 +1 would love a tutorial!maybe contact CMIFVX? (I have their contact info should you need it) 1 Share this post Link to post Share on other sites
