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. o ALLEGRO_PRIM_POSITION - Position information, can be stored in any supported fashion o ALLEGRO_PRIM_COLOR_ATTR - Color information, stored in an ALLEGRO_COLOR(3). The storage field of ALLEGRO_VERTEX_ELEMENT is ignored o 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). o 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.
