al_transpose_transform(3)

NAME
al_transpose_transform - Allegro 5 API

SYNOPSIS

        #include <allegro5/allegro.h>
        void al_transpose_transform(ALLEGRO_TRANSFORM *trans)

DESCRIPTION
Transposes the matrix of the given transform. This can be used for inversing a rotation transform. For example:

        al_build_camera_transform(camera, 0, 0, 0, x, y, z, xu, yu, zu)
        al_copy_transform(inverse, camera)
        al_transpose_transform(camera)
        // Now "inverse" will be a transformation rotating in the opposite
        // direction from "camera". Note that this only works if the camera
        // position is 0/0/0 as in the example.
