# rotate_x()¶

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

## Examples¶ ```1 2 3 4 5``` ```def setup(): py5.size(100, 100, py5.P3D) py5.translate(py5.width//2, py5.height//2) py5.rotate_x(py5.PI/3.0) py5.rect(-26, -26, 52, 52) ``` ```1 2 3 4 5``` ```def setup(): py5.size(100, 100, py5.P3D) py5.translate(py5.width//2, py5.height//2) py5.rotate_x(py5.radians(60)) py5.rect(-26, -26, 52, 52) ```

## Description¶

Rotates around the x-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_x(PI/2)` and then `rotate_x(PI/2)` is the same as `rotate_x(PI)`. If `rotate_x()` 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: rotateX

## Syntax¶

```rotate_x(angle: float, /) -> None
```

## Parameters¶

• angle: float - angle of rotation specified in radians
