Class

PShape

Name

rotateX()

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 x-axis each time the mouse is pressed
  s.rotateX(0.1);  
}
Description Rotates a shape around the x-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 rotateX(HALF_PI) and then rotateX(HALF_PI) is the same as rotateX(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.
Syntax
sh.rotateX(angle)
Parameters
sh PShape: any variable of type PShape
angle float: angle of rotation specified in radians
Returns none
