Wiggly: Spacetime Optimization for Animating Deformable Objects

Wayne Wu, Aditya Abhyankar

In this project, we implement the paper Animating Deformable Objects Using Sparse Spacetime Constraints (2014) by Schulz et al. The main idea of the paper is to use spacetime optimization with "wiggly" splines to generate natural oscillatory motions for deformable objects. We've implemented the paper as a modular Houdini toolkit that provides flexibility to users while maintaining proceduralism. The core algorithm of the paper was implemented in C++ using HDK, while two additional SOP nodes were introduced to facilitate the full workflow. I was specifically responsible for the design and implementation of the full workflow in Houdini.
