[[Cubic Bezier curves are described by 4 2D control points
|
|
(https://en.wikipedia.org/wiki/B%C3%A9zier_curve).
|
|
For each control point, the X coordinate is an input value and the Y coordinate is the
|
|
corresponding output value.
|
|
The first one, P0, is set to $[(0,0)]: The input $[0.0] is mapped to the $[0.0] output.
|
|
The last one, P3, is set to $[(1,1)]: The input $[1.0] is mapped to the $[1.0] output.
|
|
The other two control points can be set through this property and control the shape of
|
|
the curve. Note that the control points do not need to be in the $[0...1] range, and
|
|
neither do the output values of the curve.
