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
Shape – handle various hair styles
Distribute strands
Create hair styles
Distribute strands
Conform strands to head
Work with clusters of hair strands
Multi-resolution techniques
Use fluid flow to define hair strand ‘paths’
Vector field
Constraints for complex hair styles
From photographs
Capture local orientations
Comparison of shaping techniques
Procedurally generate style
Pseudo-randomSemi-automatic
Physically based methodEnergy minimization
Hair dynamics
Allow common hair solon operations
Wetting, Blow-drying, etc.
Hair simulation
Mechanics: curl, elasticity, cross section
Hair strandchain of rigid links v. spring-
dampers
Comparison of simulation techniques
Particle physicsFluid dynamics
Use guide strands for animationThen interpolate for dense hair
