Motion doodles

TLDR

The paper introduces a novel system that allows users to sketch the motion of a character. The system works by having users sketch a character, then drawing a continuous sequence of lines, arcs, and loops that are parsed and mapped to parameterized motions reflecting the sketch’s location and timing, supporting 18 motion types in 2D and a subset in 3D. The system is unique for its cursive motion specification, enabling fast experimentation and ease of use for non‑experts.

Abstract

In this paper we present a novel system for sketching the motion of a character. The process begins by sketching a character to be animated. An animated motion is then created for the character by drawing a continuous sequence of lines, arcs, and loops. These are parsed and mapped to a parameterized set of output motions that further reflect the location and timing of the input sketch. The current system supports a repertoire of 18 different types of motions in 2D and a subset of these in 3D. The system is unique in its use of a cursive motion specification, its ability to allow for fast experimentation, and its ease of use for non-experts.
