    • Disclosed is an animation method of deformable objects using an oriented material point and generalized spring model. The animation method comprises the following steps of: modeling a structure of a deformable object into oriented material points and generalized springs; initializing forces and torques acting on the material points, calculating the forces acting on the material points owing to collision of the material points and gravity, calculating the spring forces and torques acting on the material points, obtaining new positions and postures of the material points; updating positions, velocities, postures and angular velocities of the material points based upon physics, and displaying and storing updated results. The oriented material point and generalized spring model of the invention contains the principle of the conventional mass-spring model, but can animate deformable objects or express their structures in more intuitive manner over the conventional mass-spring model. Also, the material point and generalized spring model of the invention can express elongate deformable objects such as hair and wrinkled cloth, which cannot be expressed in the prior art, so as to animate features of various objects.
    • 公开了使用定向材料点和广义弹簧模型的可变形物体的动画方法。 动画方法包括以下步骤:将可变形物体的结构建模成定向材料点和广义弹簧; 初始化作用在材料点上的力和扭矩,计算由于材料点和重力的碰撞而作用在材料点上的力,计算作用在材料点上的弹簧力和扭矩,获得材料点的新位置和姿态; 基于物理学更新材料点的位置,速度,姿态和角速度,以及显示和存储更新的结果。 本发明的定向材料点和广义弹簧模型包含常规质量弹簧模型的原理,但可以以更直观的方式对可变形物体进行动画化或表达其结构,超过常规质量弹簧模型。 此外,本发明的材料点和广义弹簧模型可以表现在现有技术中不能表达的诸如毛发和起皱布的细长可变形物体,以便对各种物体的特征进行动画化。
