One Point Perspective Study
A basic perspective study illustrating three sides of a box rendered in one point perspective. You can move points A through E to change the shape of the box or the location of the vanishing point (it's especially interesting when A is inside the front of the box, or when D and E are switched). Currently has a couple subtle glitches. Note that the foreshortened grid on the side of the box is drawn correctly using a construction that lends itself well to creating correctly foreshortened guide grids when drawing with paper and pencil. More on this later.
