A Unified Analysis of Penalty-Based Collision Energies
(ACM Association for Computing Machinery, 2023)
We analyze a wide class of penalty energies used for contact response through the lens of a reduced frame. Applying our analysis to both spring-based and barrier-based energies, we show that we can obtain closedform, ...
Lifted Curls: A Model for Tightly Coiled Hair Simulation
(ACM Association for Computing Machinery, 2023)
We present an isotropic, hyperelastic model specifically designed for the efficient simulation of tightly coiled hairs whose curl radii approach 5 mm. Our model is robust to large bends and torsions, even when they appear ...
