I’d like to know what techniques people use to deal with limited precision problems. For example, if you have a virtual space that is hundreds of kilometers in size, movement and interaction in the environment can get a little shakey because of limited coordinate precision.

I’m aware that portals and tiling methods are used, but these could be employed more for managing complexity - it may not be for precision reasons. Does anyone encounter the precision/jitter problem when trying to build large continuous environments? If so, how do you deal with it?

Spmeone has already pointed me at a 2002 article by Oneil which was the sort of thing I am after. Any other articles/papers?

Yeah, there’s one more that I think is exactly what you’d be looking for. There’s a whole section on the precision issue and how it was dealt with in the game dungeon masters

A good reference and, yes, that is the sort of thing I was after.
Hopefully I’ll find some more like that - I’ll keep following the trail :(
