When making a 3D game I realise you can get away with using any scale, for example 0.000001 can be 1 meter or 100 can be one meter. Its just important that its all constant, well is there any optimum scale that should be used? Like if your using 0.00000001 as a meter then soemthing moves 1cm then the acuracy of a float might throw a wobbly over this and mess up your game. However usign a scale too big can have the same effect so I was just wondering whats the best.
Would be great if anyone knows of some articles on this but if not what do you normally use .
