Deformable Object with Naive Mass-Spring-Damper Model

A simulation of deformable object using mass-spring-damper network.

A naive implementation:

The picture above shows a node with 8 links with uniform stifness and damping coefficient.

Force on each node contributed by the the 8 links is computed, then the result is used to update the position of the node.
