This is my mass spring softbody model.

Each of the red dots is a node and each of the black lines is a spring. The node has a mass, so it is called the mass spring model.

In each timestep, the springs force some acceleration on the nodes. This is calculated with Hooke’s Law, which is \(F_s = -k \cdot s\), where \(k\) is displacement and \(s\) is spring stiffness.

This simulation is quite fun to play with. For more ideas to use this and more explanation, go here: Mass-Spring Model Video
