- Public Member Functions inherited from MeshVS_DataSource
virtual Standard_Boolean GetGeom (const Standard_Integer ID, const Standard_Boolean IsElement, TColStd_Array1OfReal &Coords, Standard_Integer &NbNodes, MeshVS_EntityType &Type) const =0
 Returns geometry information about node or element ID is the numerical identificator of node or element IsElement indicates this ID describe node ( if Standard_False ) or element ( if Standard_True ) Coords is an array of co-ordinates of node(s). For node it is only 3 numbers: X, Y, Z in the strict order For element it is 3*n numbers, where n is number of this element vertices The order is strict also: X1, Y1, Z1, X2,...., where Xi, Yi, Zi are co-ordinates of vertices NbNodes is number of nodes. It is recommended this parameter to be set to 1 for node. Type is type of node or element (from enumeration). It is recommended this parameter to be set to MeshVS_ET_Node for node. More...
 
virtual Standard_Boolean GetGeomType (const Standard_Integer ID, const Standard_Boolean IsElement, MeshVS_EntityType &Type) const =0
 This method is similar to GetGeom, but returns only element or node type. More...
 
virtual Standard_Boolean Get3DGeom (const Standard_Integer ID, Standard_Integer &NbNodes, Handle< MeshVS_HArray1OfSequenceOfInteger > &Data) const
 This method returns topology information about 3D-element Returns false if element with ID isn't 3D or because other troubles. More...
 
virtual Standard_Address GetAddr (const Standard_Integer ID, const Standard_Boolean IsElement) const =0
 This method returns pointer which represents element or node data structure. This address will be saved in MeshVS_MeshEntityOwner, 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 node or element IsElement indicates this ID describe node ( if Standard_False ) or element ( if Standard_True ) More...
 
virtual Standard_Boolean GetNodesByElement (const Standard_Integer ID, TColStd_Array1OfInteger &NodeIDs, Standard_Integer &NbNodes) const =0
 This method returns information about nodes this element consist of. ID is the numerical identificator of element. NodeIDs is the output array of nodes IDs in correct order, the same as coordinates returned by GetGeom(). NbNodes is number of nodes (number of items set in NodeIDs). Returns False if element does not exist. More...
 
virtual const TColStd_PackedMapOfIntegerGetAllNodes () const =0
 This method returns map of all nodes the object consist of. More...
 
virtual const TColStd_PackedMapOfIntegerGetAllElements () const =0
 This method returns map of all elements the object consist of. More...
 
virtual Standard_Boolean GetNormal (const Standard_Integer Id, const Standard_Integer Max, Standard_Real &nx, Standard_Real &ny, Standard_Real &nz) const
 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. Id is the numerical identificator of only element! Max is maximal number of nodes an element can consist of nx, ny, nz are values whose represent co-ordinates of normal (will be returned) In the redefined method you can return normal with length more then 1, but in this case the appearance of element will be more bright than usual. For ordinary brightness you must return normal with length 1. 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...

 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...
