vec_cross()

vec_cross	(	struct vector *	vdest,
		const struct vector	v1,
		const struct vector	v2
	)

Returns the cross of two vectors in the first parameter.

struct vector vdest;
vec_cross(&vdest, v1,v2);

Parameters

[out]	vdest	Sum vector = v1 + v2.
[in]	v1	vector.
[in]	v2	vector.

                                                                                   {


  vdest->x = v1.y*v2.z -v1.z*v2.y;
  vdest->y = v1.z*v2.x -v1.x*v2.z;
  vdest->z = v1.x*v2.y -v1.y*v2.x;
