3D Interactive Polygon Viewer

In this project, I was asked to implement a 3D interactive polygon viewing using C++ and OpenGL functions. I should load a 3D polygon defined by a triangular mesh (.OFF format), calling OpenGL functions to manipulate the polygon. These include translation, rotation, and scaling, all controlled by the left button of the mouse. If the key ‘t’ is hit, then moving the mouse with left button pressed will translate the object. Similarly the key ‘r’ and ‘s’ will initiate rotation and scaling if the left mouse button is pressed and the mouse moves. Another goal in this project was to create menus and invoke associated actions.
