NAME

       ALLEGRO_PRIM_ATTR - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro_primitives.h>

              typedef enum ALLEGRO_PRIM_ATTR

DESCRIPTION

       Enumerates the types of vertex attributes that a custom vertex may have.

       · ALLEGRO_PRIM_POSITION    -    Position    information,    can    be   stored   only   in
         ALLEGRO_PRIM_SHORT_2, ALLEGRO_PRIM_FLOAT_2 and ALLEGRO_PRIM_FLOAT_3.

       · ALLEGRO_PRIM_COLOR_ATTR - Color information, stored in an  ALLEGRO_COLOR(3alleg5).   The
         storage field of ALLEGRO_VERTEX_ELEMENT is ignored

       · ALLEGRO_PRIM_TEX_COORD   -  Texture  coordinate  information,  can  be  stored  only  in
         ALLEGRO_PRIM_FLOAT_2 and ALLEGRO_PRIM_SHORT_2.  These coordinates are normalized by  the
         width  and  height  of  the  texture,  meaning  that the bottom-right corner has texture
         coordinates of (1, 1).

       · ALLEGRO_PRIM_TEX_COORD_PIXEL - Texture coordinate information, can  be  stored  only  in
         ALLEGRO_PRIM_FLOAT_2  and  ALLEGRO_PRIM_SHORT_2.   These  coordinates  are  measured  in
         pixels.
