Resetting the state of a 3D vector
Русская версия / Russian version
The function for BGC_FP32_Vector3:
inline void bgc_fp32_vector3_reset(BGC_FP32_Vector3* const vector);
The function for BGC_FP64_Vector3:
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:
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
#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;
}
