# Resetting the state of a 3D vector

[Русская версия / Russian version](reset-rus.md)

The function for **BGC_FP32_Vector3**:

```c
inline void bgc_fp32_vector3_reset(BGC_FP32_Vector3* const vector);
```

The function for **BGC_FP64_Vector3**:

```c
inline void bgc_fp64_vector3_reset(BGC_FP64_Vector3* const vector);
```

These functions set all coordinates of 3D vectors to 0.

Each of these functions is equivalent to the following lines of code:

```c
vector->x = 0;
vector->y = 0;
vector->z = 0;
```

This function is good for setting up the initial state of a 3D vector.

### Parameters

| Parameter | Direction | Description                                              |
| --------- | --------- | -------------------------------------------------------- |
|  vector   |    out    | A pointer to a vector which coordinated must be set to 0 |

You should pass only valid pointers in the parameter *vector*. The NULL (0) value is considered invalid.

### Example

```c
#include <stdio.h>
#include <basic-geometry.h>

int main()
{
    BGC_FP32_Vector3 v;

    bgc_fp32_vector3_reset(&v);

    printf("x = %f, y = %f, z = %f\n", v.x, v.y, v.z);

    return 0;
}
```
