Hi Steve, This is an error in the documentation - it should specify that the cross function is only defined for vectors with three components, i.e.:
* vec3 cross(vec3 a, vec3 b); //Returns the cross product of vector *a* with vector *b*.* (This is because mathematically, the cross product is only defined for vectors in three-dimensional space). Sorry for the confusion - we'll update the documentation to make this clear. Please let us know though if you still have problems when dst(), A() and B() are all three-component vectors.
