Class | PShape
Name | ### rotateY()
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);
    }
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 pass P3D or OPENGL as a third parameter into the size() method as shown in the example above.
