curvePoint()

Examples

noFill()
curve(5, 26, 5, 26, 73, 24, 73, 61)
curve(5, 26, 73, 24, 73, 61, 15, 65)
fill(255)
ellipseMode(CENTER)
steps = 6
for i in range(steps):
    t = i / float(steps)
    x = curvePoint(5, 5, 73, 73, t)
    y = curvePoint(26, 26, 24, 61, t)
    ellipse(x, y, 5, 5)
    x = curvePoint(5, 73, 73, 15, t)
    y = curvePoint(26, 24, 61, 65, t)
    ellipse(x, y, 5, 5)

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 points on the curve, and b and c are the control points. 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 point on the curve
b	float: coordinate of second point on the curve
c	float: coordinate of third point on the curve
d	float: coordinate of fourth point on the curve
t	float: value between 0 and 1
