cross_product(3)		 Allegro manual 		cross_product(3)

NAME
     cross_product, cross_product_f - Calculates the cross product. Allegro game
     programming library.

SYNOPSIS
     #include <allegro.h>

     void cross_product(fixed x1, y1, z1, x2, y2, z2, *xout, *yout, *zout);

     void cross_product_f(float x1, y1, z1, x2, y2, z2, *xout, *yout, *zout);

DESCRIPTION
     Calculates  the  cross product (x1, y1, z1) x (x2, y2, z2), storing the re-
     sult in (*xout, *yout, *zout). The cross product is perpendicular	to  both
     of the input vectors, so it can be used to generate polygon normals.
