al_transform_coordinates_3d_projective(3)

NAME

al_transform_coordinates_3d_projective - Allegro 5 API

SYNOPSIS

    #include <allegro5/allegro.h>
    void al_transform_coordinates_3d_projective(const ALLEGRO_TRANSFORM *trans,
       float *x, float *y, float *z)

DESCRIPTION

Transform x, y, z as homogeneous coordinates. This is the same as using al_transform_coordinates_4d(3) with the w coordinate set to 1, then dividing x, y, z by the resulting w. This will provide the same coordinates Allegro will draw to when a projective transform is in effect as set with al_use_projection_transform(3).

Parameters:

•   trans - Transformation to use

•   x, y, z - Pointers to the coordinates
