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

Syntax

bezier_point(a: float, b: float, c: float, d: float, t: float, /) -> float

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
