Besides changing the face of animation by bringing the world the invention of the Rotoscope, as well as the concept and animation technique of "Follow the Bouncing Ball" sing-alongs, Max Fleischer and his studio also pioneered a revolutionary technique in animation, known as the “Stereoptical Process”.
In this process, a circular, 3-D model of a background - a diorama - is built to the scale of the animation cells. It allowed for a spectacular sense of depth and dimension, long before Ub Iwerks came up with the Multiplane. Within the model setup, the animation cells could be placed at varying levels from the scenery, and even between objects, so that foreground elements could pass in front of them, adding to the dimensional effect. It was an effective method for panning and tracking shots, which would require a turn of the table with each photographed cell of animation.
Every minute of this #figuredrawing was a struggle. (that’s not about sex or the relative attractiveness of the model, more about my own struggle with getting my hands to render what’s in front of me.)
