bezier(85, 20, 10, 10, 90, 90, 15, 80)
fill(255)
steps <- 10
for (i in 0:steps) {
    t <- i/steps
    x = bezierPoint(85, 10, 90, 15, t)
    y = bezierPoint(20, 10, 90, 80, t)
    ellipse(x, y, 5, 5)
}

Description

Evaluates the Bezier at point t for points a, b, c, d. The parameter t varies between 0 and 1, a and d are points on the curve, and b and c are the control points. This can be done once with the x coordinates and a second time with the y coordinates to get the location of a bezier curve at t.

Syntax

bezierPoint(a, b, c, d, t)

Parameters

a	float: coordinate of first point on the curve
b	float: coordinate of first control point
c	float: coordinate of second control point
d	float: coordinate of second point on the curve
t	float: value between 0 and 1
