# rotate_y()#

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

## Examples# ```def setup():
py5.size(100, 100, py5.P3D)
py5.translate(py5.width//2, py5.height//2)
py5.rotate_y(py5.PI/3.0)
py5.rect(-26, -26, 52, 52)
``` ```def setup():
py5.size(100, 100, py5.P3D)
py5.translate(py5.width//2, py5.height//2)
py5.rect(-26, -26, 52, 52)
```

## Description#

Rotates 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() function. Coordinates are always rotated around their relative position to the origin. Positive numbers rotate in a clockwise direction and negative numbers rotate in a counterclockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling `rotate_y(PI/2)` and then `rotate_y(PI/2)` is the same as `rotate_y(PI)`. If `rotate_y()` is run within the `draw()`, the transformation is reset when the loop begins again. This function requires using `P3D` as a third parameter to size() as shown in the example.

Underlying Processing method: rotateY

## Signatures#

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