Booleans: think BIG!

Resolution is also a problem for large models that are a long way from the origin (eg a metre sized object constructed 10 km away from origin). The resolution is spending most of its bits in defining the kilometres and less on the resolution of the model. Here move the object to (000) and perform actions, then if really needed move back to its 'true' position.

Most games and simulators provide a double precision matrix to position an object; then single precision facets are accurately placed relative to each other as they are all near the origin (000).
