title: How does tension relate to cubic spline interpolation?
body: <p>How does tension relate to cubic spline interpolation? I am referring to <a href="http://www.codeproject.com/KB/graphics/BezierSpline.aspx" rel="nofollow">this article</a> for cubic spline interpolation. The tension factor t=0 is for the first and t=1 for the last knot point. But where can we substitute the other tension values, like 0.1, 0.2, etc., in the cubic spline? Can anyone direct me to any helpful references?</p>
