Please see HfFluidDemo.cpp for examples of how to use the height field fluid along with buoyant collision shapes. The implementation is still lacking in my ways: 1) Need to complete more collision algorithms for buoyant collision shapes 2) Support compound buoyant shapes 3) The buoyancy model isn't that great 4) Fluid volume can be lost over time
