Display Windows

There are two display windows showing two different views of our world of rectangles. The display window on the left shows all the rectangles in our world along with the boundaries of the projection window initially drawn in white. Normally the current projection window is not part of the geometry and, therefore, is not visible. However, it is drawn here to help understand its role in the rendering pipeline.

The display window on the right shows the area within the current projection window. Initially this includes all rectangles in our world. The windows are updated as you change values in the parameter input window and make selections in the selection panel. There are no interactive controls attached to these windows.
