Diary During Summer Vacation 5

A very good progress has been made after a hardworking week: our Knot A Problem program has now got four views including Perspective view, Top view, Right view and Front view. This makes the program much more professional and makes operations on creating knots much eaiser. Each view has its own matrices that allow the view to zoom in, zoom out and pan move of camera. A mouse clike on a view makes the view activated and hence the allow keys etc. can only affect this activated view. Press Key 1 & 4 is to switch the display from one view to 4 view.
