rotate()

Rotates the entire coordinate system around the origin

Example

translate(width/2, height/2)
rotate(frameCount * 0.5)
trect(50, 50, 100, 100)

Syntax

rotate(angle)

InputDescription

angle

the angle of rotation in radians/degrees depending on angle mode

What is actually happening in the above example is 👇

Description

The rotate() function is used to rotate the coordinate system by a specified angle about the current origin. This means that any subsequent drawing or transformation function will be affected by this rotation.

Positive angles will rotate the plane from +x to +y, so:

  • In BOTTOM_RIGHT coordinate system, positive angles rotate counter-clockwise.

  • In BOTTOM_LEFT coordinate system, positive angles rotate clockwise.

Negative angles rotate the plane from +x to -y
