Naeem Posted April 21, 2012 Share Posted April 21, 2012 Hi, I am working on a FLIP fluid simulation and I'd like to give it a choppy wave like look without using a displacement map. The reason I'd like to do this at SOP level is so that I can measure the height of the wave to generate foam, spray and particle splashes. I tried using a Mountain SOP but couldn't get the look I wanted. Any ideas? Thanks. Naeem. Quote Link to comment Share on other sites More sharing options...
Netvudu Posted April 22, 2012 Share Posted April 22, 2012 (edited) For a nice fast choppy wave I would definitely got for HOT. What about applying it to the Fluid surface result of the FLIP simulation? That would give a SOP surface you can tweak in SOPs or even better a VOPSOP. Afterwards you can calculate convexity for the wave to get a cusp attribute than you can use as a source for particles.

Naeem Posted April 22, 2012 Author Share Posted April 22, 2012 (edited) Yea I thought about using the Ocean SOP/VOPSOP from HOT on the Particle Fluid mesh, however I am using Houdini 12 (12.0.581) on Linux x64 and there is no compiled version available for that yet. Hence, I was thinking about the alternatives. Edited April 22, 2012 by Naeem Quote Link to comment Share on other sites More sharing options...
nran Posted April 22, 2012 Share Posted April 22, 2012 (edited) There is way to use Filp to make "choppy wave" like HOT does, but it's cost too much... you can make custom vel curve, and put this curve "inside" flip, and make flip to pick up the initial velocity from the curve, and by turning the velocity up and down to control the strength of choppy. I got an example here but i only want to use this method to make "moving flip" to collide with the boat not the final choppy effect.Hope this will help Edited April 22, 2012 by nran Quote Link to comment Share on other sites More sharing options...

I'll check it out and see how it goes. Naeem. Quote Link to comment Share on other sites More sharing options...
