Name

rotate()

Examples
example pic
translate(width/2, height/2);
rotate(PI/3.0);
rect(-26, -26, 52, 52);
Description Rotates an object 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 clockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling rotate(PI/2) and then rotate(PI/2) is the same as rotate(PI). If rotate() is called within the draw(), the transformation is reset when the loop begins again. Technically, rotate() multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by the pushMatrix() and popMatrix().
