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
