#include <nitro/gx/g3_util.h>
void G3_LookAt( const VecFx32 * camPos, const VecFx32 * camUp, const VecFx32 * target, MtxFx43 * mtx );
This function sets the matrix mode to Position/Vector mode and sets the camera matrix as the current matrix.
When mtx is not NULL, the camera matrix will also be set in *mtx. There is no need to
normalize *camUp.
The matrix that is set up is shown below:

camPos |
Pointer to the camera position vector |
camUp |
Pointer to the camera up vector |
target |
Pointer to the camera focal point |
mtx |
Pointer to the 4x3 matrix |
None
