Detailed Description

sixDoFRigidBodyMotionRestraints model. Linear Spring-Damper system.

Spring-damper system for restraint. Acts as a "soft" rope when the distance between anchor and refAttachmentPt exceed the restLength, a system of spring-damper is activated to simulate a soft rope de-acceleration
