Operations between dimensions [RESOLVED]

Could we find distances between points of different dimensions. If so, how?

If you are talking 2D vs 3D now...nope. But you can to one of two tricks to "do" it...


You can define the 2D coordinate as a 3D coordinate where you say Z is 0 or something.

Or you can dicard the Z coordinate of the 3D object, and calculate the distance only with the X and Y coordinate the normal way...

Thanks. :)
