sascha Posted July 3, 2006 Share Posted July 3, 2006 I'm looking for a way to simulate a sand castle disintegrating in water. How would you simulate disintegrating sand in Houdini? Quote Link to comment Share on other sites More sharing options...

sascha Posted July 3, 2006 Author Share Posted July 3, 2006 A jet of water is hitting a sand tower which disintegrates like semi-dank sand. Quote Link to comment Share on other sites More sharing options...
Marc Posted July 3, 2006 Share Posted July 3, 2006 I think the first problem you're going to need to address is how to render that volume of sand. If you've done that then the actual sim might not be too difficult. It all kinda depends on how you'll be rendering the sand though. A particle sand solution would be very different from a surface solution. M Quote Link to comment Share on other sites More sharing options...

FrankFirsching Posted July 3, 2006 Share Posted July 3, 2006 If you're not affraid of some coding, there is the paper called "Animating sand as a fluid" from last years siggraph. It's available (together with the complete Master Thesis of Yongning Zhu) at http://www.cs.ubc.ca/~rbridson/ Quote Link to comment Share on other sites More sharing options...
peship Posted July 4, 2006 Share Posted July 4, 2006 Yeah, Frank said it all. You will need some sort of fluid sim. Try RealSlow ... errr i mean RealFlow. I think it will help you ... slow There is another liquid thing for Maya and MAX - Glu3D - it has an option to automaticly fill objects with liquid, then just turn off the collision and you will have your effect. It is pretty buggy, but should be ok for your castle. Quote Link to comment Share on other sites More sharing options...

brandonY Posted July 7, 2006 Share Posted July 7, 2006 i did this in maya... it was a pretty simple process, and im sure it wouldn't be bad in houdini. http://www.brandonyoungdesign.com/download...efx/dist_V5.mov Quote Link to comment Share on other sites More sharing options...
