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.

What is anamorphosis in the context of art?

• A technique to create abstract art

• A method to depict three-dimensional views on two-dimensional surfaces

• A style of painting using only black and white

• A form of digital art creation

Which artist is known for creating the first known anamorphic drawing?

• Vincent van Gogh

• Leonardo da Vinci

• Raphael

• Michelangelo

In perspective drawing, what happens to parallel lines that are not parallel to the canvas?

• They diverge away from each other

• They converge to a vanishing point

• They remain parallel

• They form a circle

How do artists typically create anamorphic drawings?

• By using only digital software

• By drawing freehand without any tools

• By using a light, grid, or strings to project an image at an angle

• By painting directly onto a window

What is the purpose of using a projector in creating anamorphic sidewalk drawings?

• To project the drawing onto the sidewalk for accurate tracing

• To add color to the drawing

• To create a shadow effect

• To display the drawing on a screen
