### rotateX()

#### 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 PI*2) or converted to radians with the radians() function. Objects are always rotated around their relative position to the origin and positive numbers rotate objects in a counterclockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling rotateX(PI/2) and then rotateX(PI/2) is the same as rotateX(PI). If rotateX() is called within the draw(), the transformation is reset when the loop begins again. This function requires using P3D as a third parameter to size() as shown in the example above.

#### Examples

• ``````size(400, 400, P3D);
translate(width/2, height/2);
rotateX(PI/3.0);
rect(-104, -104, 208, 208);``````
• ``````size(400, 400, P3D);
translate(width/2, height/2);
• `rotateX(angle)`
• `angle``(float)`angle of rotation specified in radians
• `void`
