Graph Chain Follow Points

{{ item.title }}

{{ definition.value }}

[!NOTE] V3 is better.

The followPoint method allows a point to follow another point, at a distance. This is a lot like constraints but with a one to one relationship in a single direction.

This graph chain stores those one to one relationships, with methods to iterate the chain in two directions. This allows use to grab the standard A -> B -> C, and C -> B -> A.

The graph can resolve a "star based" configuration:

A      C
  \   /
    B
    |
    D
    |
    E

Each connection is given in a pair, from an origin node (the head)

head = B

B -> C
B -> D [ -> E ]
D -> E
B -> A
