> Returns the quaternion that is spherically linearly interpolating a to b, by a t factor of 0.0f-1.0f

```c
SHZ_INLINE shz_quat_t shz_quat_slerp(shz_quat_t q, shz_quat_t p, float t) SHZ_NOEXCEPT;
```

Returns the quaternion that is spherically linearly interpolating `a` to `b`, by a `t` factor of `0.0f-1.0f`.

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `q` | `shz_quat_t` |  |
| `p` | `shz_quat_t` |  |
| `t` | `float` |  |

## Returns

`shz_quat_t`
