Allowing user control of the momentum and forces provides a powerful and intuitive editing tool for dynamic motions. To make a higher jump, for example, the user simply increases the linear momentum in the vertical direction, while our system automatically calculates a motion that maintains both the same landing position and physical plausibility. Our key insight is using trajectory optimization based on normalized dynamics to simultaneously propagate momentum and force space changes. We demonstrate our approach with edits of long sequences of dynamic actions, including kicks, jumps, and spins.Categories and Subject Descriptors (according to ACM CCS): I.3.6 [Computer Graphics]: Methodology and Techniques-Interaction techniques I.3.7 [Computer Graphics]: Three-Dimensional Graphics and Realism- AnimationEditing Dynamic Human Motions via Momentum and Force
