The pseudo-physics system uses minimalist particle-based physics and values of the gait pattern to generate the sinusoidal-like ballistic movement of the pelvis observed in nature. While the spine model uses simple geometry-based calculations and 3D Hermite curves to generate a flexible spine model, giving the animated creatures more agility. Our final system is totally controllable by the user in order to generate any desired style.I.3.7 [Computer Graphics]Three Dimensional Graphics and RealismAnimation
