# ALLEGRO\_VERTEX(3alleg5)

Allegro 5 API

## 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
