    • timeOfImpact

      public final void timeOfImpact(TimeOfImpact.TOIOutput output, TimeOfImpact.TOIInput input)
      Compute the upper bound on time before two shapes penetrate. Time is represented as a fraction between [0,tMax]. This uses a swept separating axis and may miss some intermediate, non-tunneling collision. If you change the time interval, you should call this function again. Note: use Distance to compute the contact point and normal at the time of impact.
      Parameters:
      output -
      input -
