I did some 3D conversions by hand, (NO A.I.), of some life drawings of mine awhile ago but forgot how I did it. So I tried a drawing I hadn't done using Photoshop. It's so so... Two of them are free-view, if you can do that, and the color one requires the red and green glasses used for anaglyph 3D.
