Spline

However, it should be possible to give more sophisticated spherical spline curves based on the de Castaljau method that are computed using multiple slerps between pairs of points and which work well for arbitrary knot positions (indeed, knot insertion methods for spline curves should suffice for this, cf Farin [1993])

These conditions provide a framework which encompasses some notable approximation kernels including splines, so-called cardinal functions, and many radial basis functions such as the Gaussians and general multiquadrics.

Machining a straight spline with a lathe. Sometimes the task of splining a shaft comes up during a repair. Instead of sending out the job, use this setup to mill the splines on a lathe.

Engineers did not think two crankshafts could be synchronized. Wood, by splining the shafts in each gear box, proved it could be done.

These packs can be holding or driving devices, depending on what they are splined to.

Splined bars are a big recent trend. Originally used in racing, the idea is to have a straight torsion bar with the ends splined like an axle and separate arms that fit on each end to mount the end links
