The shearY() function in p5.js is used to shear a shape or object around the y-axis. The object is sheared by the amount specified by the angle parameter. For proper functioning of angles should be specified in the current angleMode. The objects are always sheared around their relative position to the origin and in a clockwise direction.
Syntax:
shearY(angle)
Parameters: This function accepts single parameter angle which stores the value of angle.
Below programs illustrate the shearY() function in p5.js:
Example 1: This example uses shearY() function to shear the object around y-axis.
function setup() {       // Create Canvas of given size     createCanvas(780, 650); }   function draw() {           // Set the background color     background(220);           // Set fill color     fill('lightgreen');           // Set stroke width     strokeWeight(5);           // Set shearY function     shearY(PI/6);           // Finally Draw the sheared rectangle     rect(30, 30, 400, 300); } |
Output:
Example 2: This example uses shearY() function to shear the object around y-axis.
function setup() {           // Create Canvas of given size     createCanvas(780, 650); }   function draw() {           // Set the background color     background(220);           // Set fill color     fill('lightgreen');           // Set stroke width     strokeWeight(5);           // Set shearY function     shearY(PI/9);           // Finally Draw the sheared     // circle of radius 80     circle(height/2, width/2, 80); } |
Output:
