Constructor & Destructor Documentation

Quaternion()

icl::geom::Primitive3DFilter::Quaternion::Quaternion ( const math::Vec3 &  v, const float  w, bool  givenInAxisAngle = false  )

inline

Constructor.

Parameters

v	vector part of the Quaternion
w	scalar part of the quaternion
givenInAxisAngle	if v and w are given in axis angle representation (flag is true), they are converted to a unit quaternion
