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.
