Compared with its former 85 degree rotation, it's a flipping. Obviously, flipping only occurs when you have a 'reference angle'. 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. grandfather clock mechanical movement kit
