隐式方法可以用于有效地建模逼真的变形对象的大约束，如刚度或时间。在具有压力的软体中，模型由弹簧连接的网格点组成，并施加压力。系统参数如弹簧常数、阻尼常数等被定义来描述可变形物体的行为。针对压力作用下的柔性体在大约束条件下无法模拟的问题，提出了用柔性体特殊力的隐式积分法来解决这一问题。结果表明，当应用较大的约束条件时，该方法可以真实地模拟柔体
The implicit approach can be used to efficiently model realistically deformable objects for large constraints such as stiffness or time. In soft bodies with pressure forces, models are composed of mesh points connected by springs and applied with pressure forces. System parameters such as spring constant, damping constant, etc. are defined to describe the behaviors of the deformable objects. Since the simulation of soft bodies with pressure force fails when the constraints are large, this paper proposes the method to solve this problem by using the implicit integration method for soft bodies with particular force. The results show that our method can realistically simulate the soft bodies when large constraints are applied
