Name

rotateY()

Class

PShape

Description

Rotates a shape around the y-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() method.

Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Subsequent calls to the method accumulates the effect. For example, calling rotateY(HALF_PI) and then rotateY(HALF_PI) is the same as rotateY(PI). This transformation is applied directly to the shape, it's not refreshed each time draw() is run.

This method requires a 3D renderer. You need to use P3D as a third parameter for the size() function as shown in the example above.

Examples

  • PShape s;
    
    void setup() {
      size(100, 100, P3D);
      s = loadShape("ohio.svg");
    }
    
    void draw() {
      background(204);
      shape(s);
    }
    
    void mousePressed() {
      // Rotate the shape around the y-axis each time the mouse is pressed
      s.rotateY(0.1);  
    }
    

Syntax

  • sh.rotateY(angle)

Parameters

  • sh(PShape) any variable of type PShape
  • angle(float)angle of rotation specified in radians

Return

  • void
