A framework for generating locomotion controllers for soft-body characters with arbitrary geometries leverages natural vibration modes for actuation. This method, coupled with a reduced-order simulation, enables efficient optimization of physically plausible movements for high-resolution deformable models, achieving optimization times ranging from minutes to under an hour and demonstrating performance largely independent of mesh resolution.
Key insights
- Natural vibration modes intrinsically capture low-energy deformations and provide an effective, low-dimensional, data-free basis for physically plausible soft-body actuation.
- Decoupling actuation and simulation into distinct reduced subspaces significantly enhances computational efficiency, allowing for the animation of high-resolution deformable characters.
- Clustering elements for rotation matrix computation within the reduced actuation energy ensures mesh-independent evaluation, further accelerating simulation and optimization.
