The usual operator symbol for a wedge product is ^ . You can use 2d wedge products to determine if one vector is to the left or the right of another one. If vector A is to the right of vector B, then, if A is to the left. If they are parallel or either of them is 0, then A ^ B = 0. In vector graphics, 2d wedge products can be used to analyze the intersection of 2 parametrized curves, e.g. for removing portions of one curve that lies to the right of another.
