Re: Control points on an arbitrary plane

Hi Petter:
If you do it axis by axis the number, you put in, is the angle in degrees and the rotational direction (looking into the direction of the respective axis) is counterclockwise for positive angles.
If you put in more components at once say rx, ry, rz the rotational axis has the direction of the vector (rx,ry,rz). If you look into this direction the rotation will be counter clockwise with the amount sqrt(rx²+ry²+rz²). This (rx,ry,rz) is therefore called an “axial vector”. My 3D imagination is not good enough, so I prefer to do it axis by axis.
In your case you did a rotation around an axis pointing (25,15,0) by an angle of
sqrt(625+225)=29.15… degrees counter clockwise, OK?
Have a nice day…
