man V3D_f (3): Floating point vertex structure used by 3d functions. Allegro game programming library.

V3D_f(3) Floating point vertex structure used by 3d functions. Allegro game programming library.

SYNOPSIS

#include <allegro.h>

typedef struct V3D_f

   float x, y, z;       - position
   float u, v;          - texture map coordinates
   int c;               - color

Like V3D but using float values instead of fixed ones. Read the description of polygon3d_f() for a description on how to obtain/use this structure.
