bezier_point()

Evaluates the Bezier at point t for points a, b, c, d.

Examples

def setup():
    py5.no_fill()
    py5.bezier(85, 20, 10, 10, 90, 90, 15, 80)
    py5.fill(255)
    steps = 10
    for i in range(0, steps+1):
        t = i / steps
        x = py5.bezier_point(85, 10, 90, 15, t)
        y = py5.bezier_point(20, 10, 90, 80, t)
        py5.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.

Underlying Processing method: bezierPoint

Signatures

bezier_point(
    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
