I want to generate an object falling into a ‘ball pit’ (see pic.) and letting it move (swim) around making the balls turn and shift place. So my question is if its possible to make a fluid based out of different objects (rgb-balls). And could a ‘swimming’ object made out of particles following a path, like in this magic-wand-particle-effect tutorial, generate the physical push to move the balls aside?
If someone could point out a good tutorial for animating this type of dynamic interactions, that would be great.
