The depth of the node in the tree, starting from 0 at the root node.
The ID of the node.
The name of the node.
The parent of the node, null if it is the root node.
Properties extracted from 3D model, with property categories containing key/value string pairs.
The sector the node is contained in.
The number of descendants of the node, plus one (counting itself).
The index of the node in the 3D model hierarchy, starting from 0. The tree is traversed in a depth-first order.
The bounding box of the subtree with this sector as the root sector. Is null if there are no geometries in the subtree.
