I am wanting to change the distribution of the particles around my surface in flip fluids. What I have is an object moving upwards through a fluid where it would push more fluid where the normals are going in the same direction as the motion. Thus I would like more particles to build up in the front or top of the object as it emerges from the liquid.
Conversely the back of the object would have less particles falling behind the object. Again I am thinking that the surface normals are opposite direction of the velocity or motion of the object.
I have included a picture of what I am attempting to do.
My thoughts are: trying is using the motion vector and the surface normal - both normalized - and adding them together and having the result used in the creation of the sdf volume value.
Comments? Suggestions? Anyone do this before?
