Any type of floor/ceil of numbers would get that to a certain degree. eg. instead of X,Y,Z being stuff like (12.3, 0.9, 3.638372) you would get (12, 1, 4) . Essentially, if you want to simulate old clunky animation you need to "compress" or "crush" your positions and such into a "less than accurate" number
