NAME¶
al_transform_coordinates_3d_projective - Allegro 5 APISYNOPSIS¶
-
#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(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:
- •
- trans - Transformation to use
- •
- x, y, z - Pointers to the coordinates
Since 5.2.4
