Name
rotate()
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 transformations 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().
Examples
size(400, 400); translate(width/2, height/2); rotate(PI/3.0); rect(-104, -104, 208, 208);
Syntax
rotate(angle)
Parameters
angle
(float)
angle of rotation specified in radians
Return
void
