Ok I got it partly somehow running, but currently I'm fighting with matrixes
which do not have an inversion-matrix, I got to algorythms on how to get the
inversion-matrix and in some rare cases they return different values, and tell
me that they can't build a rotation matrix.
The strange thing with that is, that rotating by 90 degree or 45 degree in one
direction is fine, but rotating it additionally into another direction also by
45 degree delivers no inversion matrixes anymore ???
However thank you all for your help, it seems to go into the right direction
now ....
