Static p5_sys::global::curvePoint

pub static curvePoint: CurvePointInternalType

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

Examples

noFill();
curve(5, 26, 5, 26, 73, 24, 73, 61);
curve(5, 26, 73, 24, 73, 61, 15, 65);
fill(255);
ellipseMode(CENTER);
let steps = 6;
for (let i = 0; i <= steps; i++) {
  let t = i / steps;
  let x = curvePoint(5, 5, 73, 73, t);
  let 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);
}

Parameters

a coordinate of first control point of the curve

b coordinate of first point

c coordinate of second point

d coordinate of second control point

t value between 0 and 1
