[Lib2geom-devel] Direction of rotations

[Maximilian A. <Anh...@gm...>]

Hi,

if I am not mistaken, one way to rotate a vector v by an angle alpha is 
the following:

    Geom::Rotate rot(alpha);
    v = v * rot;

But this yields a rotation in the clockwise (i.e., mathematically 
negative) direction. Is this intentional or am I just using the 
constructs in the wrong way?
