The createVector() function in p5.js is used to create the new p5 vector which contains both magnitude and direction. This provides a two or three-dimensional vector, specifically a geometric vector.
Syntax:
createVector([x], [y], [z])
Parameters: This function accepts three parameters as mentioned above and described below:
- x: This parameter stores the x component of the vector.
- y: This parameter stores the y component of the vector.
- z: This parameter stores the z component of the vector.
Below programs illustrate the createVector() function in p5.js:
Example 1: This example uses createVector() function to draw a line.
Javascript
function setup() { // Create a Canvas createCanvas(500, 550); } function draw() { // Vector initialisation // using createVector t1 = createVector(10, 40); t2 = createVector(411, 500); // Set background color background(200); // Set stroke weight strokeWeight(2); // line using vector line(t1.x, t1.y, t2.x, t2.y); translate(12, 54); line(t1.x, t1.y, t2.x, t2.y); } |
Output:
Example 2: This example uses createVector() function to draw a circle.
Javascript
function setup() { // Create a Canvas createCanvas(500, 550); } function draw() { // Vector initialisation // using createVector t1 = createVector(10, 40); t2 = createVector(41, 50); // Set background color background(200); // Set stroke weight strokeWeight(2); // Fill yellow fill('yellow'); // ellipse using vector ellipse(t1.x*millis() / 1000 * 20, t1.y, t2.x+100, t2.y+100); } |
Output:
