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)

(PShape)
