As you can see by the tests added, colors and normals have an ordering that is specifically constrained within the FVF. To clarify, by saying that the booleans are redundant, do you mean to say that, say, if I have a normal element, I should iterate back through all declaration elements that have already been processed and check for a prior color element, and then return D3DERR_INVALIDCALL? Again, for the case of two color elements or two normal elements, are you suggesting I do the same (iterate through all past elements)? Wouldn't, in this case, a boolean be more efficient? hasPosition I apologize does not need to be there. Just trying to clarify your points regarding your comments re booleans and specialty of colors and normals.
