void G3_LookAt( const VecFx32 * camPos, const VecFx32 * camUp, const VecFx32 * target, MtxFx43 * mtx );
camPos | Camera Position Vector Pointer |
camUp | Camera Up Vector Pointer |
target | Camera Focal Point Pointer |
mtx | The pointer to a 4x3 matrix. |
None.
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 is as shown below.
