After reading the article @
http://www.drizzle.com/~scottb/gdc/continuous-world.htm
i realised that there are some questions i should better decide before designing everything.
- at which point the world gets too big so that the flowing point coordinates are too unprecise ?
Could this be solved by a kind of "master position nodes" ?
Nodes which are parents of each other at an equal distance and every other objects position is calculated as a position from the current master position node.
If a object moves too far from its current master position node it picks the next best suited position node as its parrent.
Sure this would eat cpu time for convertion position relative to master nodeA to position relative to nodeB but it would avoid the loss of precission which would occur if i work only with absolute position values.
Another problem is : would the irrlicht engine alow such things ?
