  1. 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)?

  3. Hey everyone, I really fell in love with some of the visuals created by Chaotic Atmospheres, link : http://chaoticatmospheres.com/flowing-city-map. They describe their process as a mix of displacement maps created in world machine all composited in PS, but I want to create and simulate this with velocity flows and possibly particles to create a more dynamic map for some of my architectural site plans. I've looked through and gathered different techniques for creating vector fields and I am a little stuck. I've used some of the techniques with manuplating vector fields with curves, creating a volume and driving trails, but the collision and erosion just hasn't produced the effect I want quite yet. With a few drawn curves on the grid, I can get a nice flow, but upon adding any more complex nurb systems, it just starts to group too many vectors. I might be going about all this wrong, but wanted to see if anyone could offer some more help or a more efficient technique. The end goal would be for the vectors to be able to be animated to visualize flow from the city boundaries outwards towards the edges. Thanks to anyone who can offer any advice/tips/help on this endeavor.
