al_transform_coordinates_3d_projective - Allegro 5 API
#include <allegro5/allegro.h>
void al_transform_coordinates_3d_projective(const ALLEGRO_TRANSFORM *trans,
float *x, float *y, float *z)
Transform x, y, z as homogeneous coordinates. This is the same as using al_transform_coordinates_4d(3alleg5) 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(3alleg5).
Parameters:
Since 5.2.4
al_use_transform(3alleg5), al_transform_coordinates(3alleg5), al_transform_coordinates_3d(3alleg5), al_use_projection_transform(3alleg5)
