ABSTRACT
In animation, hair styles can often be modeled without the consideration of physics. One of the side effects of this workflow is that external forces such as gravity will deform the groom from the designed shape when simulated. We present a simple optimization algorithm that preloads the rest shape to compensate for the external forces to maintain the groom shape during simulation. The algorithm provides artistic control over how much force is compensated for at each vertex.

Holding the shape in hair simulation
SIGGRAPH '19: ACM SIGGRAPH 2019 TalksHair simulation models are based on physics, but require additional controls to achieve certain looks or art directions. A common simulation control is to use hard or soft constraints on the kinematic points provided by the articulation of the scalp or ...
A layered wisp model for simulating interactions inside long hair
Proceedings of the Eurographic workshop on Computer animation and simulationThis paper presents a method for animating long hair while modelling both interactions between the hair and the character's body and between different hair wisps. Our method relies on a layered model paradigm. Hair is structured into a number of ...
