Py5Shape.rotate_y()

Py5Shape.rotate_y()#

Rotates the shape around the y-axis the amount specified by the angle parameter.

Examples#

def setup():
    global s
    py5.size(100, 100, py5.P3D)
    s = py5.load_shape("bot.svg")


def draw():
    py5.background(204)
    py5.scale(0.2)
    py5.shape(s, py5.width//2, py5.height//2)


def mouse_pressed():
    # rotate the shape around the y-axis each time the mouse is pressed
    s.rotate_y(0.1)

Description#

Rotates the shape around the y-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted from degrees to radians with the radians() method.

Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Subsequent calls to the method accumulates the effect. For example, calling rotate_y(HALF_PI) and then rotate_y(HALF_PI) is the same as rotate_y(PI). This transformation is applied directly to the shape, it’s not refreshed each time draw() is run.

This method requires a 3D renderer. You need to use P3D as a third parameter for the size() function as shown in the example.

Underlying Processing method: PShape.rotateY

Signatures#

rotate_y(
    angle: float,  # angle of rotation specified in radians
    /,
) -> None
