This one was fairly simple to draw on paper but turned out to be quite complex to pull off when recreating the concept on the computer. When drawing by hand I often end up unintentionally distorting proportions and angles just to get the figures to fit together, cheating if you will, something that cannot be done if you are drawing correctly using perspective points.
If you travel along the top and then along the bottom you will keep going in the same direction, in or outwards. At the same time the top and bottom are connected vertically at several places.
As a bonus today I’m also attaching a picture I put together by superimposing all the different steps I had saved while plotting the lines. I found it pretty interesting to look at. Actually, it might be the best way yet to visualize my technique and give you an idea of the amount of work that is involved. Enjoy :)
