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.
