Name

quadraticVertex()

Description

Specifies vertex coordinates for quadratic Bézier curves. Each call to quadraticVertex() defines the position of one control point and one anchor point of a Bézier curve, adding a new segment to a line or shape. The first time quadraticVertex() is used within a beginShape() call, it must be prefaced with a call to vertex() to set the first anchor point. This function must be used between beginShape() and endShape() and only when there is no MODE parameter specified to beginShape(). Using the 3D version requires rendering with P3D (see the Environment reference for more information).

Examples

  • size(400, 400);
    noFill();
    strokeWeight(16);
    beginShape();
    vertex(80, 80);
    quadraticVertex(320, 80, 200, 200);
    endShape();
    Image output for example 1
  • size(400, 400);
    noFill();
    strokeWeight(16);
    beginShape();
    vertex(80, 80);
    quadraticVertex(320, 80, 200, 200);
    quadraticVertex(80, 320, 320, 320);
    vertex(320, 240);
    endShape();
    Image output for example 2
