No, that is not exactly right.  Technically it should be

        if ((triangle_classification & 3) == 3) {

to be foolproof in general.  However, in this case the above should work, as well as the slightly simplified:

       triangle_classification = classification[0]
                | classification[1]
                | classification[2];
  
       if (!triangle_classification) {

As I said, not exactly reader friendly.
