p5.js | dist() Function

• Last Updated : 17 Jan, 2020

The dist() function calculates the Euclidean distance in 2D or 3D. Means the p5.js | dist() Function is used to measure the distance between two points in 2D or 3D. Below is the formula for distance in 2D and 3D.

• 2D formula: • 3D formula: Syntax:

dist(x1, y1, x2, y2)
dist(x1, y1, z1, x2, y2, z2)

Parameters:

• x1: These parameters holds the x-coordinate of the first point.
• y1: These parameters hold the y-coordinate of the first point.
• z1: These parameters hold the z-coordinate of the first point.
• x2: These parameters hold the x-coordinate of the second point.
• y2: These parameters hold the y-coordinate of the second point.
• z2: These parameters hold the z-coordinate of the second point.

Return value: Distance between two points.
Example: This example calculates and prints the distance between a fixed point and the cursor.

 function setup() {    // Create a canvas    createCanvas(400, 400);}  function draw() {    // set background color    background(50);    // coordinates of the fixed point    var x1 = 200;    var y1 = 200;    // coordinates of the cursor    var x2 = mouseX;    var y2 = mouseY;    // set line color and weight    stroke(255);    strokeWeight(2);    // draw a line connecting 2 points    line(x1, y1, x2, y2);    fill("red");    // draw a circle centered at each point    ellipse(x1, y1, 10);    ellipse(x2, y2, 10);    // calculate the distance between 2 points    d = dist(x1, y1, x2, y2);    noStroke();    fill("lightgreen");    // set text size and alignment    textSize(20);    textAlign(CENTER);    // display the distance calculated    text("distance = "+ str(d), 200, 350);}
