The topology module allows you to make abstract descriptions of the spatial layout of pieces of the region you are modelling. Partitions define shapes such as layers, cubes, spheres, and meshes. Regions put partitions together by arranging them hierarchically. The topology is formed as a tree of regions, that end downstream in a terminal set of partitions.

To initiate the topology, the network size hint is passed to the root region, which subdivides it for their children to make an initial attempt to lay themselves out. Once handed back the initial layouts of their children, parent regions can propose transformations to finalize the layout. If any required transformation proposals fail to meet the configured constraints, the layout process fails.



The root Group receives the network X, Y, and Z. A Group is an inert region and simply passes the network boundaries on to its children. The Voxels loads its voxels, and positions them absolutely, ignoring the network boundaries. The Stack passes the volume on to the Layers who fill up the space and occupy their thickness. They return their layout up to the parent Stack, who in turn proposes translations to the layers in order to stack them on top of the other. The end result is stack beginning from the network starting corner, with 2 layers as large as the network, with their respective thickness, and absolutely positioned voxels.
