This work is an experimental video created from a research about “Rotoscope” and “Computer Geometry”. Rotoscope is known as an traditional technique for creating animation invented in 1905 by Max Fleischer in which animators traced the actors outline over live-action film to make a realistic cartoon. Through research, we rediscovered and developed this technique from a new point of view by extracting various information, not just outline, from a live film and created experimental films since 2003.
In “ballet rotoscope”, by extracting the movement of a dancing ballerina, we created a animation of locus drawn in the air, and dancing geometric figures, composed with a documentary picture. The geometric figures were created by connecting the movement of ballerina’s joints by using algorithm of computer geometry(such as “convex hull”,and “Delaunay diagram”). Our aim was to represent a complete new type of beauty, by showing the interaction of abstract animation with realistic movements and documentary film.
