p5.js | dist() Function

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

  • 2D formula:
      d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}
  • 3D formula:
      d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2+(z_1-z_2)^2}

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 ponints.
Example: This example calculates and prints the distance between a fixed point and the cursor.

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);
