1. A hybrid hair simulation method using a computer graphics system, the method comprising: generating a plurality of modeled hair strands using a processor of the computer graphics system, each hair strand comprising: a plurality of particles; and a plurality of spring members coupled in between the plurality of particles; determining a first position and a first velocity for each particle in the plurality of modeled hair strands using the processor; coarsely modeling movement of the plurality of modeled hair strands as an incompressible fluid with a continuum fluid solver using the processor; and computing self-collisions of the plurality of modeled hair strands with a discrete collision model using the processor.
