   object to worldspace translation
  If I wanted to translate a vertex in object space to world space would I just do;p * worldMatrix?   
Quote:If I wanted to translate a vertex in object space to world space would I just do;p * worldMatrix?Yes. (Assuming, that is, that p is a row vector and worldMatrix is a 4x4 matrix, or that multiplication is implemented in such a way that the input vector and matrix are treated as having these dimensions. The latter is often the case in practice, although in these cases it's better, IMO, to use a named function rather than to overload the * operator.)
