3D coordinates for MIX_SetTrack3DPosition.
Defined in <SDL3_mixer/SDL_mixer.h>
typedef struct MIX_Point3D
{float x; /**< X coordinate (negative left, positive right). */
float y; /**< Y coordinate (negative down, positive up). */
float z; /**< Z coordinate (negative forward, positive back). */
} MIX_Point3D;
The coordinates use a "right-handed" coordinate system, like OpenGL and OpenAL.
This struct is available since SDL_mixer 3.0.0.
