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:
Below programs illustrate the bezier() function in p5.js:
Example 1: This example uses bezier() function to draw a bezier() curve.
function setup() {
// Create canvas size
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);
} |
Example 2: This example uses bezier() function with all parameters to draw a bezier() curve.
function setup() {
// Create canvas size
createCanvas(150, 150);
} function draw() {
// Set the background color
background(0, 0, 0);
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);
