Hi, I''m trying to think up a nice object-oriented solution for something and would appreciate the help of a guru or two! I''m basically just displaying a bezier patch at the moment and would like to add an edit mode to my program which toggles the display of the patch''s control points and permits the user to drag them around. So far I just have a BPatch class which renders the patch. I''m looking for a OOP way of representing the states of the application (view,edit,maybe some more later on) and a control mechanism for the editable control points, rather than shoving it all in one class. Any suggestions would be must appreciated. Thanks <Fish>{
