# shz_vec3_rotate_y

Source: https://sh4zam.com/api/vector/shz_vec3_rotate_y/

```c
SHZ_INLINE shz_vec3_t shz_vec3_rotate_y(shz_vec3_t vec, float radians) SHZ_NOEXCEPT;
```

Rotates the given 3D vector about the Y axis by the given angle in radians.

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `vec` | `shz_vec3_t` |  |
| `radians` | `float` |  |

## Returns

`shz_vec3_t`

## Warnings

- This routine should only be used for one-off rotations of a single vector. To rotate multiple vectors in a batch, use the XMTRX API.
