Farmfield Posted June 2, 2016 Share Posted June 2, 2016 Oh yeah, that's cool. And I love me some Lindsey Stirling. How did you setup the contract/expand thingie at 0:52-1:03..? I played around with contractions when I was knee deep in these setups but I never got anything good working. I had also an idea to have some parts contracting and others expanding, and with some noise on the point positions, get the pattern move on the surface like from undercurrents. But I kinda got stuck before I had to move onto other RnD... Quote Link to comment Share on other sites More sharing options...
Adam Ferestad Posted June 2, 2016 Share Posted June 2, 2016 Honestly, I have no idea why it does that, but I figured out how to work with it, so I was able to use it. The only part that should be animating the growth motion. What I am animating over the whole thing is just the final multiplication for the force, but when it approaches 0 it begins contracting. I didn't change the system itself from the previous file I posted, so maybe you can figure out what is doing it in there. Please share if you figure it out.

stevegh Posted June 3, 2016 Share Posted June 3, 2016 (edited) Love this thread. Thanks everyone for posting your files, really interesting. I only had a couple minutes to play with this at work but here is a 3D mesh version. You don't get quite the interesting shapes we've seen here but I am hoping someone can do something with it from here. Literally just using remeshing instead of resampling. Tried putting points in the volume to avoid intersections but the shapes are even less interesting... 3dgrowth.002.hiplc Edited June 3, 2016 by stevegh wrong file 1 Quote Link to comment Share on other sites More sharing options...
rbowden Posted June 30, 2016 Share Posted June 30, 2016 Is it possible for one of the mods to rename this topic back to the original name? Kinda weird for this to be stickied and called none now...I guess the OP didn't like being called out. Quote Link to comment Share on other sites More sharing options...
Farmfield Posted August 27, 2016 Share Posted August 27, 2016 Just wanted to post a variant of the very first setup using a per segment resampling rather than resampling the whole line, so the parts moving gets an extra push which yields a bit more "oily" look to it. I was using the per segment resampling for a completely different thing when I came to think about testing it with this differential line setup. diff.curve.variant.v1.hiplc 1 Quote Link to comment Share on other sites More sharing options...
eetu Posted August 29, 2016 Share Posted August 29, 2016 I'll drop my tests here as well; There's also a hip on the next page. Quote Link to comment Share on other sites More sharing options...
Farmfield Posted August 29, 2016 Share Posted August 29, 2016 Crazy cool, Eetu. I will absolutely dig into that hip. Quote Link to comment Share on other sites More sharing options...
Solitude Posted August 29, 2016 Share Posted August 29, 2016 Eetu's initial explanation is how I got started on mine. I was close to figuring it out but that made the light bulb click for me. So simple, yet extremely helpful explanation. Quote Link to comment Share on other sites More sharing options...
Thomas Helzle Posted September 2, 2016 Share Posted September 2, 2016 After 20 years of CG I'm finally learning Houdini - most fun I ever had with a software. ;-) Followed the Entagma Tutorial (thanks guys!) and went further from there to see if I can make the growth avoid certain areas. I used a black and white image mapped to the geometry and scaled the pscale attribute with it to make the lines "stop" at the borders. Leads to an interesting effect when rendering, as if the slightly overlapping areas were fading out. Cheers, Tom 5 Quote Link to comment Share on other sites More sharing options...
Thomas Helzle Posted September 21, 2016 Share Posted September 21, 2016 Learned a lot more in the meantime - today I coded a custom threading solution to have the growth look more like rough yarn and less like something wormy... ;-) A big thanks to everybody in this forum - it's absolutely splendid how much one can learn from just lurking!!!

Farmfield Posted September 27, 2016 Share Posted September 27, 2016 (edited) Looking at it I come back to something I played around with but never got going (-well), that's contracting lines. Edit - LOL, actually wasn't very complicated, as the curve resamples, if you start pushing it in one direction, it'll downres itself into oblivion. differential.curve.contraction.v1.hiplc Edited September 27, 2016 by Farmfield 1 Quote Link to comment Share on other sites More sharing options...

DaJuice Posted October 1, 2016 Share Posted October 1, 2016 What an awesome and fun thread. Thanks to everyone for sharing and a big thanks to the guys at Entagma. I took their setup and modified it a bit to hold the shape of the starting geometry better. There are some issues when Selective Remeshing (remeshing by group) is enabled. Every once in a while the Remesh SOP will generate a model with patches of inverted normals. Haven't figured out a clean way of dealing with that as the Facet SOP and PolyDoctor don't work a hundred percent of the time. hollowCube.mp4 differentialGrowth_hollowCube.hip 2 Quote Link to comment Share on other sites More sharing options...

Dave Stewart Posted October 3, 2016 Share Posted October 3, 2016 Nice setup and render DaJuice! We have a sweet 3D printer here at work, figured it was about time I learned how to print something... First of many I hope! --Dave 2 Quote Link to comment Share on other sites More sharing options...
