# Three-dimensional vectors

[Русская версия / Russian version](vector3-rus.md)

There are two types of 3D vectors in the library:
- **BGC_FP32_Vector3** - vector using single-precision floating-point numbers
- **BGC_FP64_Vector3** - vector using double-precision floating-point numbers

Structure definitions:

```c
    typedef struct
    {
        float x, y, z;
    } BGC_FP32_Vector3;

    typedef struct
    {
        double x, y, z;
    } BGC_FP64_Vector3;
```

The fields *x*, *y* and *z* are the coordinates of a 3D vector.
