Description Evaluates the curve at point t for points a, b, c, d. The parameter t may range from 0 (the start of the curve) and 1 (the end of the curve). a and d are the control points, and b and c are points on the curve. As seen in the example above, this can be used once with the x coordinates and a second time with the y coordinates to get the location of a curve at t.
Syntax
curvePoint(a, b, c, d, t)
Parameters
a float: coordinate of first control point
b float: coordinate of first point on the curve
c float: coordinate of second point on the curve
d float: coordinate of second control point
t float: value between 0 and 1
Returnsfloat
