Method Detail

addSpring

public void addSpring(SpringNode node)

Add a spring between the given node and this node.

Parameters:

node - The new node instance to connect to this one

resetNaturalLengths

public void resetNaturalLengths()

Regenerate the natural lengths based on the current separation between this node and it's connections. This will also reset the current direction vector back to zero again.
