The transformation from Euler angles is achieved by exploiting the nature of the quaternion structure and using fundamental half-angle formulae from trigonometry. First, the Euler angles version of the LOS guidance ... WebA Slerp path is, in fact, the spherical geometry equivalent of a path along a line segment in the plane; a great circle is a spherical geodesic . Oblique vector rectifies to Slerp factor. More familiar than the general Slerp formula is the case when the end vectors are perpendicular, in which case the formula is p0 cos θ + p1 sin θ. did andy griffith really play the guitar
