Typewrite "projective_geometry_demo(sz)", in Matlab console with sz the size of the chessboard, sz >= 3, to run and display the figure comparing 2D top view of the chessboard, and its projective geometry view.
Some objects like circle, a parabola, and an hyperbole are also drawn.
In projective geometry they have the property that all of them appear as a circle.
Change the projection parameters (view point, projection matrix) to test your own and change the output !
