NAME
ALLEGRO_VERTEX - Allegro 5 API
SYNOPSIS
#include <allegro5/allegro_primitives.h>
typedef struct ALLEGRO_VERTEX ALLEGRO_VERTEX;
DESCRIPTION
Defines the generic vertex type, with a 3D position, color and texture coordinates for a single texture.
Note that at this time, the software driver for this addon cannot render 3D primitives. If you want a 2D
only primitive, set z to 0. Note that you must initialize all members of this struct when you're using
it. One exception to this rule are the u and v variables which can be left uninitialized when you are
not using textures.
Fields:
• x, y, z - Position of the vertex (float)
• u, v - Texture coordinates measured in pixels (float)
• color - ALLEGRO_COLOR(3alleg5) structure, storing the color of the vertex
