I'd like to bump this - I'm looking into the same thing, and any sort of example that handles a dynamic shape in a funky way would be appreciated. Right now I'm doing jit.bfg and just crossing my fingers for awesomeness, so perhaps something a bit more... predictable than that? :)
Have a look at the mesh.shatter and surfing.noise examples. Beyond that, you could also consider using jit.gen to manipulate matrices for jit.gl.multiple. Making really complex meshes is tricky without connectivity information.
