      q1 - if non-null contains portion of curve from .5->1

    • subdivide

      public void subdivide(double t, Quadradic q0, Quadradic q1)
      Subdivides this Quadradic curve into two curves at given t.
      Parameters:
      q0 - if non-null contains portion of curve from 0->t.
      q1 - if non-null contains portion of curve from t->1.
