I am not sure if this will help at all but from a quick read on the
net it seems that the Kass and Miller model treats the fluid as a
bunch of tubes under the surface.  Now if the tubes represent the mesh
points then cannot the new mesh surface defined by using the old mesh
plus a vector field that is representative of the velocity of the
fluid.  If this be the case then you can use the vtkWarpVector class
to warp the original mesh as per the velocity vector field and then
display the new surface.  This most probably wont work for splashing
though.
