1. Computer animation Hair “A Survey on Hair Modeling: Styling, Simulation, and Rendering,” K. Ward, F. Bertails, T.-Y. Kim S. Marschner, M.-P. Cani, M. Lin

2. Motion – dynamic grouping and splitting of hair clusters, collision of hairs, seconday motion due to head motion Properites – coarse v. fine, dry v. wet, stiff v. loose, oily v. clean, hair strand types Shape – handle various hair styles User Control – over hair style, properties

3. Shape – handle various hair styles Distribute strands Create hair styles

4. Distribute strands

5. Conform strands to head

6. Work with clusters of hair strands

7. Multi-resolution techniques

8. Use fluid flow to define hair strand ‘paths’

9. Vector field Constraints for complex hair styles

10. From photographs Capture local orientations

11. Comparison of shaping techniques

12. Procedurally generate style Pseudo-random Semi-automatic

13. Physically based method Energy minimization Hair dynamics

14. Allow common hair solon operations Wetting, Blow-drying, etc.

15. Hair simulation Mechanics: curl, elasticity, cross section

16. Hair strand chain of rigid links v. spring-dampers

18. Comparison of simulation techniques

19. Particle physics Fluid dynamics

20. Use guide strands for animation Then interpolate for dense hair model

21. Hair strips to represent hair clusters

23. Level of detail representation for animation

24. Adaptive clusters, merge and split

25. Hair rendering
