Need help with water particles

Hi, how do I simulate water particles in Farseer? So for example, I have a glass with and ice cube. When I fill it with the water particles, the ice cube will float to the top. Thanks.

Currently we don't support interactive particles. You could create small circles at the bottom of the glass and use a special shader to render then like water.

We do support an AABB (Axis Aligned Bounding Box) for simulating buoyancy. See the WaterSampleXNA for an example.

Ah, ok. Doing more searching, I think the graphical technique is called metaballs. I want it to work with an arbritary-shaped container so I guess I'll have to find out how to make the circle vs ice cube collision water-like.

You could simply change the code that checks whether or not a shape should be affected by a controller to instead check against a polygon. Let me know if your interested.

If you could provide more info on how I can do that, that'd be great. Thanks.
