Setup for the 2PtV and 3pt Heads-in-Boxes

Here is animated GIF that shows how to setup for the Sophie drawing. Because a baby's head is closer to a cube proportionally than an adult's, this method yields a cube, which is a lot easier to get to than the 2x3x3 box. If you add a little extra height and depth to her cranium, above and at the back of the cube, while keeping her eyes at the level of the original halfway line, you will be correcting both the head shape and proportions to that of a baby. That's how I've got it figured out anyway.

Either the top red line or the bottom could be the horizon.

Your cube will be more useful if you make it smaller than mine and keep it fairly near the center of the red square. Thanks to Keiko for asking the question that spurred me to do this.

And here is an animation that goes through the steps we learned for 3pt. Use the same procedure for upshots and downshots. Just turn the paper upside down at the end of the procedure to do an upshot.

Click on  the images to see them animate bigger. Both loop indefinitely.

Thanks to Luis Deliz for his contribution to this method of constructing a 2x3x3 box.

Here is an example of a head shape carefully put inside the 3pt box.  Making the box occupy a larger portion of your equilateral triangle than I demonstrated risks greater distortion than this. You'll note that this head already appears a bit top-heavy. You can reduce the area of your head box within the equilateral a lot without losing that 3pt feel.

The above box exists fully in downshot, that is, below the horizon. It is essential that you not allow the head to cross or even very closely approach the horizon in either the 2ptV (Sophie) or 3pt (Francis) drawings! These drawings must be upshot or downshot.
