Position-based Shape Constraint for Real-time Hair Simulation

• Matheus de Moraes Cavazotti UFPR
• André Luiz Pires Guedes UFPR

Resumo

In this work we present a method to simulate curly hair with its spring-like characteristics in real-time, while maintaining the strand inextensibility. By using the position-based simulation framework and expanding on previous works on the same topic, a new constraint is devised to keep the curls shape. We share our results and stablish parallels with other related works.
