A transformation that rotates about a particular axis in space, defined by two endpoints.
PN_stdfloat get_angle() const
Returns the angle of rotation, in degrees counterclockwise about the axis as seen from point a.
void set(const LPoint3d &point_a, const LPoint3d &point_b, PN_stdfloat angle)
Defines the rotation.
TypeHandle is the identifier used to differentiate C++ class types.
