rotate = rotieren, drehen general syntax: rotate <wx,wx,wz>this causes a rotation of an object arround the appropriated coordinate axis of the three basic directions by an angle of wx degrees arround the x axis by an angle of wy degrees arround the y axis and by an angle of wz degrees arround the z axis. Attention: The rotations are not applied relative of any local axes of symetriy through the center of an object and the rotations will be applied in the writen order! |
"rotate< 0,90, 0>" causes a rotation arround the y axis by 90 degrees (lefthanded positive).
"rotate< 0,90,45>" first causes a rotation arround the y axis by 90 degrees and then
a rotation arround the z axis by 45 degrees.
"rotate< 0, 0,45> rotate< 0,90, 0>" first causes a rotation of 45 degrees arround the z axis
followed by a rotation of 90 degrees arround the y axis.
Be aware:
Sequential rotations arround different axes
are not interchangeable!
This means the result depends on the order in which we apply these rotations!
High potential of frustration if we are not carefully enough!!!.
