I want to “reasonably simulate” a liquid that is being poured into a trough or mold of arbitrary shape, e.g. a channel sculpted into a mesh plane.
I don’t want to spend hours on a fluid-simulation.
I’m free-thinking about some kind of effect that uses metaball-particles. I can sort-of describe what would be needed according to solid-body physics rules, as though the metaballs were, say, little heavy marbles. I don’t mind using Blender Game-Engine and bullet and so-on.
So, I am basically looking for what might be easiest and what might be already done. “Boids,” for instance? It does not have to be photorealistic; the folks are not going to be admiring the beautiful fluid-shapes; there will be no “droplets.” I know that I can do it by laboriously hand-animating shape keys in a mesh.
