Detailed Description

template<index_t DIMENSION>
class RINGMesh::GeoModelBuilderRepair< DIMENSION >

Try repairing a supposedly invalid GeoModel.

Remove colocated vertices in all GeoModelMeshEntity. Remove degenerated edges and polygons in Surfaces and Lines.

Warning: This function will by no mean fix all errors in a GeoModel It has been tested on a very small number of geomodels.

private

Checks if an edge is degenerate.

An edge is degenerate if both vertices are colocated.

Parameters

[in]	line	Line to check the edge `edge`.
[in]	edge	edge index in Line `line`.
[in]	colocated_vertices	contains the colocated mapping of the Line.

Returns: true if the edge is degenerate. Else false.

template<index_t DIMENSION>

void RINGMesh::GeoModelBuilderRepair< DIMENSION >::remove_colocated_entity_vertices_and_update_gm ( )

private

Remove the colocated vertices in all the GeoModelMeshEntities within the GeoModel. GeoModelMeshEntities without any vertex anymore (after the removal of the vertices) are removed off the GeoModel.

◆ remove_degenerate_polygons_and_edges()

template<index_t DIMENSION>

void RINGMesh::GeoModelBuilderRepair< DIMENSION >::remove_degenerate_polygons_and_edges ( std::set< gmme_id > & to_remove )

private

Remove degenerate polygons and edges from the Surface and Line of the geomodel.

Parameters

[out] to_remove gmme_t of the entities (Surface and Line) of the geomodel that are empty once degenerate entities are removed

Precondition: Colocated vertices have already been removed

void RINGMesh::GeoModelBuilderRepair< DIMENSION >::remove_degenerate_polygons_and_edges_and_update_gm ( )

private

Remove the degenerated polygons in all the Surfaces and all the degenerate edges in all the Lines within the GeoModel. Degeneration is due to colocated vertices. Surfaces and Lines without any vertex anymore (after the removal of the vertices) are removed off the GeoModel.

TODO when it will works, use GeoModelBuilderRemoval::remove_entities_and_dependencies
