Re: [Algorithms] Smooth movement of camera along a path

[Will P. <wi...@cs...>]

Catmull-Rom splines interpolate all control points, so they would be worth
checking out.  Look at:

http://graphics.cs.ucdavis.edu/CAGDNotes/Catmull-Rom-Spline/Catmull-Rom-Spline.html

The standard graphics textbooks have better expositions than this web page
if you have access to them.
