Method and system for graphical hairstyle generation using statistical wisp model and pseudophysical approaches

A method for graphical hairstyle generation comprising steps of:

• a) constructing a density map, a length map, and a protrusion map for hairs;
• b) tuning the global parameters including the number of wisps and the number of strands;
• c) editing the geometry of the prototype strand by modeling the prototype strand with a 3D spline curve;
• d) tuning the wisp parameters including the length distribution, deviation radius function, and fuzziness value;
• e) setting up the styling force field;
• and
• f) tuning the deformation parameters including the bending stiffness and the density threshold.

A system for interactive hairstyle generation using statistical wisp model and pseudo-physical approaches comprising:

• a) a hair strand generating module for generating hair strands and wisps by controlling the statistical properties of hair using a statistical wisp model;
• b) a hair deformation solving module for solving the hair deformation due to gravity and collisions between the hair by a pseudo-physical approaches using a styling force field;
• c) a hair styling module for styling the hair by superimposing a constraint force field with the styling force field and solving the hair deformation;
• d) a hair rendering module for rendering the hair strands using probability density functions to represent the randomness of hair color;
• and
• e) a styling force field constructing module for constructing a styling force field using procedural approach with a means for editing a vector field.
