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); } |
