> Returns a 3D vector that is linearly interpolated from a to b by the given 0.0f-1.0f factor, t

```c
SHZ_INLINE shz_vec3_t shz_vec3_lerp(shz_vec3_t a, shz_vec3_t b, float t) SHZ_NOEXCEPT;
```

Returns a 3D vector that is linearly interpolated from `a` to `b` by the given `0.0f-1.0f` factor, `t`.

## Parameters

| --- | --- | --- |
| `a` | `shz_vec3_t` |  |
| `b` | `shz_vec3_t` |  |
| `t` | `float` |  |

## Returns

`shz_vec3_t`
