p5.js | bezier() function

The bezier() function in p5.js is used to draw cubic Bezier curve on the screen. These curves are defined by a series of anchor and control points.

Syntax:

bezier( x1, y1, x2, y2, x3, y3, x4, y4 )
or
bezier( x1, y1, z1, x2, y2, z2, x3, y3, z3, x4, y4, z4 )

Parameters: The function accepts twelve parameters as mentioned above and described below:

  • x1 This parameter stores the x-coordinate for the first anchor point
  • y1 This parameter stores the y-coordinate for the first anchor point
  • x2 This parameter stores x-coordinate for the first control point
  • y2 This parameter stores y-coordinate for the first control point
  • x3 This parameter stores x-coordinate for the second control point
  • y3 This parameter stores y-coordinate for the second control point
  • x4 This parameter stores x-coordinate for the second anchor point
  • y4 This parameter stores y-coordinate for the second anchor point
  • z1 This parameter stores z-coordinate for the first anchor point
  • z2 This parameter stores z-coordinate for the first control point
  • z3 This parameter stores z-coordinate for the second control point
  • z4 This parameter stores z-coordinate for the second anchor point
  • Below programs illustrate the bezier() function in p5.js:

        createCanvas(150, 110);
    }
       
    function draw() {
      
        // Set the background color
        background(220);
          
        noFill();
          
        // Set the stroke color
        stroke(0, 0, 0);
          
        // Bezier function 8 parameters 
        // except z-coordinate
        bezier(85, 20, 10, 10, 160, 90, 50, 80);
    }

        noFill();
          
        // Set the stroke color
        stroke(255);
          
        // Bezier function with all 12 parameters
        bezier(150, 150, 0, 100, 100, 0, 100, 0, 0, 0, 100, 0);
    }
