◆ _transformVector()

template<class Derived >
EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE QuaternionBase< Derived >::Vector3 Eigen::QuaternionBase< Derived >::_transformVector ( const Vector3 v) const

return the result vector of v through the rotation

Rotation of a vector by a quaternion.

Remarks
If the quaternion is used to rotate several points (>1) then it is much more efficient to first convert it to a 3x3 Matrix. Comparison of the operation cost for n transformations:
  • Quaternion2: 30n
  • Via a Matrix3: 24 + 15n
