   Cross versus multiplication
  Hi,  Could someone please explain the difference between multiplying two vectors, and taking the cross product of them.  I not sure I really understand it.Thanks Levi

I not sure I really understand it.Thanks LeviThere are several ways of "multiplying" vectors. The cross product is one of those ways.   ;  This is a good starting point: http://mathworld.wolfram.com/VectorMultiplication.htmlThe scalar product is probably the most frequently used vector multiplication. The cross product only exists for vectors in three dimensions, and it's useful to compute normals.;  Yes, I am using it to compute normals, I was just wondering if there was a different way of multiplying them.  I'll look at the link.  ThanksLevi
