Name rotate() Examples translate(width/2, height/2); rotate(PI/3.0); rect(-26, -26, 52, 52); Description Rotates a shape 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() function. Objects are always rotated around their relative position to the origin and positive numbers rotate objects in a clockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling rotate(HALF_PI) and then rotate(HALF_PI) is the same as rotate(PI). All tranformations are reset when draw() begins again. Technically, rotate() multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by the pushMatrix() and popMatrix(). Syntax rotate(angle); Parameters angle float: angle of rotation specified in radians Returns None Usage Web & Application Related rotateX() rotateY() rotateZ() translate() scale() pushMatrix() popMatrix() radians()

Processing was initiated by Ben Fry and Casey Reas. It is developed by a small team of volunteers.
