Extract Topology allows direct access to topological information in the Assemblage.

inputs

• AOa - the Assemblage

outputs

• hO - [as Tree] Handle Occupancy. -1: occluded, 0: free, 1: connected
• nO - [as Tree] neighbour AssemblyObject: index of neighbour AO if connected or occluded, -1 otherwise
• nH - [as Tree] neighbour Handle: index of neighbour Handle if connected, -1 otherwise

options

notes

The outputs are structured as a tree, where each branch represents an AssemblyObject and the items in the lists respect the Handle order used at the AssemblyObject creation

The connectivity outputs (hO, nO, nH) are consistent with the connectivty info on Handle.
