I'm trying to decide how best to implement a coordinate-based system.

1) First, for longterm referencing of position, is it better to partition space using (a) infinitely small points, or (b) finite, space-filling polyhedra (such as cubes, rhombic dodecahedra, or truncated octahedra)?

2) Second, should free objects in open space be allowed to move (a) in any direction and/or for any distance, or (b) only from center to center of a polyhedral point?

(Note that 1b and 2a are not mutually exclusive. One might allow an object to move with no respect to one's partioning of space, and then determine which partition the object is in for other purposes. Whether this is ever a reasonable approach, I'm not sure of.)
