Ballet Rotoscope

In “ballet rotoscope,” by extracting the movement of a dancing ballerina, Masahiko Satoh and his team created an animation of a locus drawn in the air and dancing geometric figures, composed with a documentary picture.

This work is an experimental video created from research about “Rotoscope” and “Computer Geometry.” Rotoscope is a traditional technique for creating animation invented in 1905 by Max Fleischer in which animators traced the actor’s outline over the live-action film to make a realistic cartoon.

Through research, Masahiko Satoh rediscovered and developed this technique from a new point of view by extracting various information, not just an outline, from a live film and creating experimental films since 2003. The geometric figures were created by connecting the movement of the ballerina’s joints by using an algorithm of computer geometry(such as “convex hull” and “Delaunay diagram”).

Masahiko Satoh represented a completely new type of beauty by showing the interaction of abstract animation with realistic movements and documentary film.
