Spherical spline interpolation
WebMar 1, 2006 · The normalised spline exhibits large variations in speed and magnitude of acceleration, whilst the spherical Bezier spline is far better behaved. These considerations are important in applications where velocities and accelerations need to moderated or estimated, notably computer animation and rigid body trajectory planning, where … WebJul 1, 2008 · In this paper, we extend Parker's (1994) spherical method to include tension and determine the Green's function for continuous curvature splines in tension on a sphere. This new Green's function allows us to rapidly implement spherical gridding with tension for situations which may include a mix of surface and gradient data constraints.
