Copying

The copy functions allow you to copy the coordinate values of one vector to another vector.

Function for BgcVector3FP32:

inline void bgc_vector3_copy_fp32(const BgcVector3FP32* from, BgcVector3FP32* to);

Function for BgcVector3FP64:

inline void bgc_vector3_copy_fp64(const BgcVector3FP64* from, BgcVector3FP64* to);

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

to->x1 = from->x1;
to->x2 = from->x2;
to->x3 = from->x3;

The from and to parameters must not be invalid pointers. The NULL (0) value is also considered invalid.

The from parameter must be a pointer to a three-dimensional vector whose coordinates are to be copied. The coordinates of the from vector will not change after the function call.

The to parameter must be a pointer to a three-dimensional vector whose coordinates are to be changed. The coordinates of the to vector will become the same as those of the from vector after the function call.

Example of use:

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

int main()
{
    BgcVector3FP32 my_vector1, my_vector3;

    bgc_vector3_set_values_fp32(-2, 7, 1, &my_vector1);

    bgc_vector3_copy_fp32(&my_vector1, &my_vector3);

    printf("x1 = %f, x2 = %f, x3 = %f\n", my_vector3.x1, my_vector3.x2, my_vector3.x3);

    return 0;
}
