International audience; Processing interactions is one of the main challenges in hair animation. Indeed, in addition to the collisions with the body, an extremely large number of contacts with high friction rates are permanently taking place between individual hair strands. Simulating the latter is essential: without hair self-interactions, strands would cross each other during motion or come to rest at the same location, yielding unrealistic behavior and a visible lack of hair volume. This chapter reviews the most recent advances to tackle the specific problems of hair collision detection and response. The solutions presented here range from simple approximations that provide hair with a volumetric behavior in real-time to dedicated algorithms for efficiently yet robustly detecting collisions between hair guides and for generating a realistic response to hair interactions.
