kgmcnamara Posted November 10, 2014 Share Posted November 10, 2014 (edited) I've always been fascinated by procedural set modeling, so I figured I'd try my hand at modeling some tropical marine life in Houdini. I'll be posting my progress here! I have started hashing out a few basic types of coral, anemone, etc. Hoping to eventually get this all into a large scene. Anemone motion test: I apologize, but I cannot currently share hip files of these scenes since they may be used in a contract.

Diego A Grimaldi Posted November 10, 2014 Share Posted November 10, 2014 Cool stuff Kevin! I expect a lot from you buddy Are you using Wire?? Quote Link to comment Share on other sites More sharing options...
kgmcnamara Posted November 20, 2014 Author Share Posted November 20, 2014 (edited) Hey Diego! Thanks, hopefully I won't disappoint Yep, I am just using a basic wire sim with constraints and wind force, super easy to set up. A little bit of progress on my anemone digital asset. Given an input curve that defines the body shape, the digital asset exposes a handful of parameters to tweak your anemone just the way you want it. Lots more to come (when I can find the time!)

kleer001 Posted November 21, 2014 Share Posted November 21, 2014 whoa, what an ambitious project. can't wait to see more! Quote Link to comment Share on other sites More sharing options...
Wooshum Posted November 30, 2014 Share Posted November 30, 2014 Cool project! I stumbled across the article below on the simulation of coral structures a while ago; It may be handy reference for your project: http://www.ploscompbiol.org/article/info%3Adoi%2F10.1371%2Fjournal.pcbi.1002849 Quote Link to comment Share on other sites More sharing options...
JonathanGranskg Posted December 1, 2014 Share Posted December 1, 2014 Great idea for a project. Can't wait to see the end result. Quote Link to comment Share on other sites More sharing options...
kgmcnamara Posted December 2, 2014 Author Share Posted December 2, 2014 (edited) Thanks Dan, that's a very cool paper. I'll give it a good read through and see if I can apply some of the techniques!

kgmcnamara Posted December 11, 2014 Author Share Posted December 11, 2014 Thanks! Looking forward to exploring more coral types and starting to put them together. Spent some time expanding the fan coral digital asset to include a two-pass space colonization that allows for a main and sub branch structure. 1 Quote Link to comment Share on other sites More sharing options...
kgmcnamara Posted December 20, 2014 Author Share Posted December 20, 2014 (edited) Using reaction diffusion to grow some new types of coral! Lots of fun exploring how to tweak the chemicals to get different types of growth. Edited December 20, 2014 by kgmcnamara 8 Quote Link to comment Share on other sites More sharing options...
kleer001 Posted January 6, 2015 Share Posted January 6, 2015 where I can I learn more about reaction diffusion in Houdini?! Quote Link to comment Share on other sites More sharing options...
paxsonsa Posted January 6, 2015 Share Posted January 6, 2015 where I can I learn more about reaction diffusion in Houdini?! Hey kleer001, I got that answer, I am not sure if Kevin is using Gray-Scotts Model but here are some sources for you along with that VEX class I mentioned before http://mrob.com/pub/comp/xmorphia/ http://www.cs.utah.edu/~gk/papers/tvcg00/node7.html http://training.cgsociety.org/course/vex-in-houdini Cheers! 1 Quote Link to comment Share on other sites More sharing options...
kgmcnamara Posted January 7, 2015 Author Share Posted January 7, 2015 Yep, I am using the gray-scott model. It's quite straightforward to implement using an attribWrangle and a SOP Solver. The links above are great resources, as well as Karl Sims' page There is an open-source library for reaction diffusion called Ready. It's extremely powerful and can be a great place to start. 1 Quote Link to comment Share on other sites More sharing options...

kgmcnamara Posted December 21, 2016 Author Share Posted December 21, 2016 (edited) Back experimenting with some coral growth! Here's an early test using an adaptation of differential mesh growth. Lots to tweak, but it's a start at growing this kind of mantipora "shelf" coral: Edited December 21, 2016 by kgmcnamara 4 Quote Link to comment Share on other sites More sharing options...
