Approximation of ’raised inverted cosine’. Diverges from real function
by less that 0.1% within the range [0..1].

It also shares some of the Raised Inverted Cosine’s key properties, having flat derivatives at 0 and 1, and the value 0.5 at x=0.5.

Function: seat-double-cubic (&rest args) ¶

This seat-shaped function is formed by joining two 3rd-order polynomial (cubic) curves. The curves meet with a horizontal inflection point at the control coordinate specified by ’inflection-point’ in the unit square.

Function: seat-double-cubic-with-linear-bend (&rest args) ¶

This is a modified version of #’seat-double-cubic.

It uses ’inflection-point’ to control the location of its inflection point along the diagonal of the unit square.

’amount-of-blend’ is used to control the how much we blend this curve with the Identity Function (y=x). This has the effect of tilting the slope of the curve’s plateau in the vicinity of its inflection point.

The adjustable flattening around the inflection point makes this a useful shaping function for lensing or magnifying evenly-spaced data.
