Calculates cross-product with vector v. The resulting vector is
perpendicular to both the current and supplied vector and overrides the
current.

@param v
the v

@return itself
Calculates cross - product with vector v . The resulting vector is perpendicular to both the current and supplied vector and overrides the current .
