Various issues with the camera about grrlib

[Crayon2000]

Hello, the GRRLIB_Camera3dSettings function is used to set values that are used by the guLookAt function in libogc. Here is the documentation in case it can help you:

/*!
 * \fn void guLookAt(Mtx mt,guVector *camPos,guVector *camUp,guVector *target)
 * \brief Sets a world-space to camera-space transformation matrix.
 *
 * \details Create the matrix \a m by specifying a camera position (\a camPos), a camera "up" direction (\a camUp), and a target
 * position (\a target).
 *
 * The camera's reference viewing direction is the -z axis. The camera's reference 'up' direction is the +y axis.
 *
 * This function is especially convenient for creating a tethered camera, aiming at an object, panning, or specifying an
 * arbitrary view.
 *
 * \param[out] mt New viewing matrix.
 * \param[in] camPos Vector giving 3D camera position in world space.
 * \param[in] camUp Vector containing camera "up" vector; does not have to be a unit vector.
 * \param[in] target Vector giving 3D target position in world space.
 *
 * \return none
 */

So nothing mentions rotation.

I think I will need to change the documentation for GRRLIB_Camera3dSettings because it is wrong since 2009:

 * @param posx x position of the camera.
 * @param posy y position of the camera.
 * @param posz z position of the camera.
 * @param upx Alpha component.
 * @param upy Alpha component.
 * @param upz Alpha component.
 * @param lookx x up position of the camera.
 * @param looky y up position of the camera.
 * @param lookz z up position of the camera.

I guess it should be replaced by something like this:

 * @param posx x position of the camera.
 * @param posy y position of the camera.
 * @param posz z position of the camera.
 * @param upx x up position of the camera.
 * @param upy y up position of the camera.
 * @param upz z up position of the camera.
 * @param lookx x position of the target.
 * @param looky y position of the target.
 * @param lookz z position of the target.

Thanks, I was wondering what the alpha component was. Changing upx, upy, and upz still didn't have the desired effect, so to rotate the camera do I have to set lookx, looky, and lookz to a point relative to the camera in the direction I want, or is there an easier way?
