Detailed Description

Class for grouping information about rotation matrices.

Determing the sense of rotation requires the rotation type and Eigenvector. Therefore it is most efficient to group all these properties so that the intermediate results can also be used.

Member Function Documentation

sg_vec3 const& ev

(

)

const [inline]

Axis direction (Eigenvector) of the corresponding proper rotation.

Only defined if abs(type()) > 1.
For type() > 0, the proper rotation is defined as r.
For type() < 0, the proper rotation is defined as -r. So for type() == -2, this is the normal to the mirror plane.

int sense

(

)

const [inline]

Sense of rotation with respect to the axis direction.

Only defined if abs(type()) > 1.
