Constructor & Destructor Documentation

GeomTopoTool()

moab::GeomTopoTool::GeomTopoTool	(	Interface *	impl,
		bool	find_geoments = false,
		EntityHandle	modelRootSet = 0,
		bool	p_rootSets_vector = true,
		bool	restore_rootSets = true
	)

Constructor (creates a GTT object) \ Construct a GeomTopoTool object and search for geometric EntitySets if they exist in the provided moab instance.

Parameters

impl	MOAB instance the GeomTopoTool will operate on.
find_geoments	if specified as True, geometric objects in the provided MOAB instance will be searched for and added to the GTT.
modelRootSet	the GTT will operate only on geometric EntitySets contained by this EntitySet. If unprovided, the default value for the modelRootSet is the MOAB instance's root set, which contains everything in the instance.
p_rootSets_vector	determines the storage datastructure used to relate geometric EntitySets to their OrientedBoundingBox (OBB) Tree roots. If set to true (default) a vector will be used to store the root sets along with an EntityHandle offset for fast lookup of the root sets. If set to false, then a map will be used to link geometric EntitySets (keys) to the OBB Tree root sets (values).
restore_rootSets	determines whether or not to restore the internal index that links geomSets to their corresponding OBB Root. Only relevant if find_geoments is true. (default = true)

Get the other (d-1)-dimensional entity bounding a set across a (d-2)-dimensional entity.

Given a d-dimensional entity and one (d-1)-dimensional entity, return the (d-1) dimensional entity across a specified (d-2)-dimensional entity. For example, given a surface, edge, and vertex, returns the other edge bounding the surface sharing the vertex. In the case of degenerate results, e.g. two loops bounding a surface and sharing a vertex, tries to step in positively-oriented direction. This won't always work; in those cases, will return MB_MULTIPLE_ENTITIES_FOUND.

In the special case where bounded is a curve, then not_this can be a vertex and across zero. This function returns the other vertex on the curve.

restore_topology_from_geometric_inclusion()

ErrorCode moab::GeomTopoTool::restore_topology_from_geometric_inclusion

(

const Range &

flat_volumes

)

Discover and store the topological relationships among a set of volumes This method may be used to discover the hierarchy that exists in a range of volumes, that have no previous sense of hierarchy, and store it according to the conventions of GeomTopoTool. The following requirements about the range of flat_volumes must be met:

1. Each volume must be represented by a single, closed surface a. The surface meshsets have triangles and vertices as members. b. For each "flat volume", there must be two meshsets: one for the volume and another for the surface that encloses it. These must be linked by a parent-child relationship. c. The SENSE_FORWARD tag on the surface meshset must be set to be the volume meshset it encloses.
2. The surfaces must not touch or overlap

After the hierarchy is established, the topological relationships between surfaces and the volumes that enclose them are set. This involves:

1. Setting parent-child relationship between surfaces and the volumes that enclose them.
2. Setting the SENSE_REVERSE tag on the surfaces to be the volume that encloses them.
