| Standard_Boolean | GetGeom (const Standard_Integer theID, const Standard_Boolean theIsElement, TColStd_Array1OfReal &theCoords, Standard_Integer &theNbNodes, MeshVS_EntityType &theType) const override |
| Returns geometry information about node ( if IsElement is False ) or element ( IsElement is True ) by co-ordinates. For element this method must return all its nodes co-ordinates in the strict order: X, Y, Z and with nodes order is the same as in wire bounding the face or link. NbNodes is number of nodes of element. It is recommended to return 1 for node. Type is an element type. More... | |
| virtual Standard_Boolean | Get3DGeom (const Standard_Integer theID, Standard_Integer &theNbNodes, Handle< MeshVS_HArray1OfSequenceOfInteger > &theData) const override |
| This method returns topology information about 3D-element Returns false if element with ID isn't 3D or because other troubles. More... | |
| Standard_Boolean | GetGeomType (const Standard_Integer theID, const Standard_Boolean theIsElement, MeshVS_EntityType &theType) const override |
| This method is similar to GetGeom, but returns only element or node type. This method is provided for a fine performance. More... | |
| Standard_Address | GetAddr (const Standard_Integer theID, const Standard_Boolean theIsElement) const override |
| This method returns by number an address of any entity which represents element or node data structure. More... | |
| virtual Standard_Boolean | GetNodesByElement (const Standard_Integer theID, TColStd_Array1OfInteger &theNodeIDs, Standard_Integer &theNbNodes) const override |

| const TColStd_PackedMapOfInteger & | GetAllNodes () const override |
| This method returns map of all nodes the object consist of. More... | |
| const TColStd_PackedMapOfInteger & | GetAllElements () const override |

| virtual Standard_Boolean | GetNormal (const Standard_Integer theID, const Standard_Integer theMax, Standard_Real &theNx, Standard_Real &theNy, Standard_Real &theNz) const override |
| This method calculates normal of face, which is using for correct reflection presentation. There is default method, for advance reflection this method can be redefined. More... | |

| virtual Standard_Boolean | GetNodeNormal (const Standard_Integer ranknode, const Standard_Integer ElementId, Standard_Real &nx, Standard_Real &ny, Standard_Real &nz) const |
| This method return normal of node ranknode of face Id, which is using for smooth shading presentation. Returns false if normal isn't defined. More... | |
| virtual Standard_Boolean | GetNormalsByElement (const Standard_Integer Id, const Standard_Boolean IsNodal, const Standard_Integer MaxNodes, Handle< TColStd_HArray1OfReal > &Normals) const |
| This method puts components of normal vectors at each node of a mesh face (at each face of a mesh volume) into the output array. Returns false if some problem was detected during calculation of normals. Id is an identifier of the mesh element. IsNodal, when true, means that normals at mesh element nodes are needed. If nodal normals are not available, or IsNodal is false, or the mesh element is a volume, then the output array contents depend on the element type: face: a normal calculated by GetNormal() is duplicated for each node of the face; volume: normals to all faces of the volume are computed (not for each node!). MaxNodes is maximal number of nodes an element can consist of. Normals contains the result. More... | |
| virtual void | GetAllGroups (TColStd_PackedMapOfInteger &Ids) const |
| This method returns map of all groups the object contains. More... | |
| virtual Standard_Boolean | GetGroup (const Standard_Integer Id, MeshVS_EntityType &Type, TColStd_PackedMapOfInteger &Ids) const |
| This method returns map of all group elements. More... | |
| virtual Standard_Address | GetGroupAddr (const Standard_Integer ID) const |
| This method returns pointer which represents group data structure. This address will be saved in MeshVS_MeshOwner, so that you can access to data structure fast by the method Owner(). In the redefined method you can return NULL. ID is the numerical identificator of group. More... | |
| virtual Standard_Boolean | IsAdvancedSelectionEnabled () const |
| Returns True if advanced mesh selection is enabled. Default implementation returns False. It should be redefined to return True for advanced mesh selection activation. More... | |
| virtual Bnd_Box | GetBoundingBox () const |
| Returns the bounding box of the whole mesh. It is used in advanced selection mode to define roughly the sensitive area of the mesh. It can be redefined to get access to a box computed in advance. More... | |

| Returns maps of entities (nodes and elements) detected by mouse click at the point (X,Y) on the current view plane, with the tolerance aTol. DMin - is out argument should return actual detection tolerance. Returns True if something is detected. It should be redefined if the advanced mesh selection is activated. Default implementation returns False. More... | |
| virtual Standard_Boolean | GetDetectedEntities (const Handle< MeshVS_Mesh > &Prs, const Standard_Real XMin, const Standard_Real YMin, const Standard_Real XMax, const Standard_Real YMax, const Standard_Real aTol, Handle< TColStd_HPackedMapOfInteger > &Nodes, Handle< TColStd_HPackedMapOfInteger > &Elements) |
| Returns maps of entities (nodes and elements) detected by mouse selection with rectangular box (XMin, YMin, XMax, YMax) on the current veiw plane, with the tolerance aTol. Returns True if something is detected. It should be redefined if the advanced mesh selection is activated. Default implementation returns False. More... | |

| Returns maps of entities (nodes and elements) detected by mouse selection with the polyline <Polyline> on the current veiw plane, with the tolerance aTol. Returns True if something is detected. It should be redefined if the advanced mesh selection is activated. Default implementation returns False. More... | |
| virtual Standard_Boolean | GetDetectedEntities (const Handle< MeshVS_Mesh > &Prs, Handle< TColStd_HPackedMapOfInteger > &Nodes, Handle< TColStd_HPackedMapOfInteger > &Elements) |
| Filter out the maps of mesh entities so as to keep only the entities that are allowed to be selected according to the current context. Returns True if any of the maps has been changed. It should be redefined if the advanced mesh selection is activated. Default implementation returns False. More... | |
