Interface CoefficientMixer


  • public interface CoefficientMixer
    Interface used to customize the way friction and restitution coefficients are mixed.

    The DEFAULT_MIXER performs the following operations for friction and restitution mixing respectively:

     sqrt(friction1 * friction2)
     max(restitution1, restitution2)
