Popular Post Wooshum Posted October 9, 2016 Popular Post Share Posted October 9, 2016 Hi All, Just wanted to share my explorations on this theme. This thread has given me the push to explore a couple of coral growth papers I have been interested in for quite a white, particularly this one: http://www.sciencedirect.com/science/article/pii/S0022519304000761 After playing around with some of the setups on this thread I built a solver based that is a bit of a mutant space colonization system - in that the coral grows towards a food source. This means you can drive the simulation to fill objects and makes it controllable from an artistic perspective. I have attached the HIP if anyone wants to play. Dan.

Farmfield Posted October 9, 2016 Share Posted October 9, 2016 Awesome work, Dan. This is probably the most realistic coral growth I've seen so far, amazingly organic. Very cool, very impressive. Quote Link to comment Share on other sites More sharing options...

Atom Posted October 9, 2016 Share Posted October 9, 2016 (edited) Thanks for sharing that one Dan! Here is the letter T as the food source. Drop down some UVs after creation and dial in the scale XY for the UVTransform. Follow that up with a tilable tech displace map and you get Orgotech or Technorganic. Here is another image using the Mantra Skin shader. Edited October 10, 2016 by Atom 3 Quote Link to comment Share on other sites More sharing options...
Farmfield Posted October 10, 2016 Share Posted October 10, 2016 Awesome stuff, Atom, very cool. And talking about the very cool, here's something very, very cool. 9 Quote Link to comment Share on other sites More sharing options...

Atom Posted October 10, 2016 Share Posted October 10, 2016 Nice work Johnny, are you using a bend on each of those letters? Quote Link to comment Share on other sites More sharing options...
Farmfield Posted October 11, 2016 Share Posted October 11, 2016 (edited) Not my work Atom - though I love you believe I'm competent enough to create that setup. That being said, if you have the coral letter model, you could probably tweak a setup like this to create a similar type of deformation.

Thomas Helzle Posted October 12, 2016 Share Posted October 12, 2016 (edited) I somehow always wanted to achieve a thinner version of the coral growth and finally succeeded today after some hints in the comments on this video: So I extended my old Entagma-based setup and replaced the resample node with a remesh and fiddled quite a long time with parameters but finally got it working - one major hint was to add some minimal noise to the points to get it out of the 2D plane. To not have it paper thin I added a poly extrude and 2 subdivisions. Mantra was too slow for me so I once again exported to Thea Render: Cheers, Tom Edited October 12, 2016 by Thomas Helzle 4 Quote Link to comment Share on other sites More sharing options...

Thanks Farmfield! :-) Took it a step further today: Took out the thickness but added veins using "Shortest Path". Rendering in Thea Render.

TobiasSteiner Posted October 30, 2016 Share Posted October 30, 2016 Hi guys. I'm having some trouble getting shading to work on parts where growth is happening if I use a "WIRE" node on only a group that contains the effected area. If I don't use the wire node I'm able to use multiple shaders assigned by group. Any tips on how to get multiple shading assignments to work when inserting a wire node? Any help is much appreciated. 3 Quote Link to comment Share on other sites More sharing options...

Farmfield Posted November 3, 2016 Share Posted November 3, 2016 I'm pretty sure the wire SOP applies it's own UV mapping and that might be what's throwing it off..? And I think the lack of response is about you not posting a scene file, from what you've said so far, it's a bit of a guessing game what is going on in the scene. If you have stuff you don't want to share, you can work around that by using a null at the end of the setup, though before the wore node, then right click and lock it - then you can delete anything accept for the last part and the shaders, so we at least have something to go on, troubleshooting this thing.

Excellent point regarding the file share. It's attached now. The base template is the Houdini to Arnold Basic Studio setup I made to share freely from my website so if you don't have Arnold when opening it you'll need to create Mantra lights, shader, and render node.

It's rather simple, check the hip file if you like. Theres a vector "self" (pointing away from the spline itself) added to all points, and a vector "surf" pointing towards points densely scattered on the collision geo but only added to points that got pushed outside of the volume. Finally another vector "straight" is added pointing to the center between the previous and the next point, effectively damping the bending. Finally I should note that the very last step of the solver is a wrangle that has an animated lerp between the previous' and current frame's shape to safely control the speed of the whole thing in one parameter. Without that it would fill the whole thing in a max of 40 frames and then slow down harshly, but it was too late to tweak the forces and I wanted to render it Cheers! BrainGrowth_v001.hipnc Love it!
