how I can simulate the TurnEntity function in mathematics?

Blitz3D Forums/Blitz3D Programming/mathematics I don't understand what you're trying to achieve
Think you're going to have to get your hands dirty with quaternions, for that one.

this is what i know so far. i posted in those two threads, too. i hope it helps.
basicaly it works as follows: using default euler rotation, you rotate the object matrix just once. once on it's x axis, THEN on the y axis and THEN on it's z axis.
using quaternions you rotate the object everytime you use TurnEntity just a bit. that will cause the effect of quaternions.
