sb526 3 Posted November 8, 2017 (edited) Hi all! Loads of cool stuff here. I'm looking for ideas/suggestions from Houdini veterans on how to recreate a process of melting or a differential erosion of the material. I have attached a screen cap of the closest example I've found in a video by Christoph Bader/Dominik Kolb called Area Contraction. Also attached a macro shot & GIF of my physical experiment of creating similar structures via melting. Sadly, I haven't been able to find any papers or simulation breakdown examples of Area Contraction or how to replicate it in Houdini. There are so many potential paths to take that I feel a bit lost - is it best to operate in volumes or VDBs? Or should I simply stick to particle solvers? FLIP liquid with attractors? FLIP liquid driven by temperature values (lava, snow, ice shelf tools)? Edited November 8, 2017 by sb526 Share this post Link to post Share on other sites
jonah@jonahtobias.com 1 Posted November 14, 2017 (edited) There's a lot more going on in that area contraction video. My guess is they're taking a base torus, filling it with particles, giving the particles a varying density attribute driven by voronoi noise, fading the density over time, converting those particles into a volume, smoothing the volume, and finally converting that volume into poly's. You can also use the vdb reshape sdf node to erode your volume and get a similar effect. Edited November 14, 2017 by jonah@jonahtobias.com Share this post Link to post Share on other sites
