Detailed Description
Options to control OrthoHubLayout.
Member Data Documentation
◆ avoidFlatTriangles
| bool dialect::OrthoHubLayoutOptions::avoidFlatTriangles = true |
If three nodes u, v, w in a graph form a triangle – i.e. a subgraph isomorphic to K3 – then we may wish to prevent the "flattening" of this triangle, i.e. the configuration of any one of the three nodes in such a way that the other two are assigned to opposite compass directions, e.g. assigning u and w to be north and south, resp., of v. To prevent this, set this option to true.
As an example of why you might want to set this option to false, consider that then the graph K4 gets a planar layout. When used in combination with routing by libavoid, flat triangles are not always bad.

◆ includeLinks
| bool dialect::OrthoHubLayoutOptions::includeLinks = false |
By default, we attempt to configure only Nodes of degree 3 or higher. The idea is that nodes of degree 2 (a.k.a. "links") be handled by a different procedure, such as the ACA algorithm. However, good results can also be obtained by performing ortho hub layout on all nodes, of any degree. If that is desired, set the includeLinks option to true.
