TED-ED: The mathematics of sidewalk illusions - Fumiko Futamura

The video explores anamorphosis, a technique in perspective art that creates 3-D illusions on 2-D surfaces. Originating in the Renaissance, it involves mathematical principles to achieve realistic views. The video explains how perspective drawings work, using the window analogy, and describes techniques for creating anamorphic art, including sidewalk drawings. It highlights the historical development of perspective art and the role of artists like Leonardo da Vinci and Hans Holbein.
