Calculate the normal of a surface defined by points <code>(v1X, v1Y, v1Z)</code>, <code>(v2X, v2Y, v2Z)</code> and <code>(v3X, v3Y, v3Z)</code>
and store it in <code>dest</code>.
@param v0X
the x coordinate of the first position
@param v0Y
the y coordinate of the first position
@param v0Z
the z coordinate of the first position
@param v1X
the x coordinate of the second position
@param v1Y
the y coordinate of the second position
@param v1Z
the z coordinate of the second position
@param v2X
the x coordinate of the third position
@param v2Y
the y coordinate of the third position
@param v2Z
the z coordinate of the third position
@param dest
will hold the result
