Constructor | |
Standard_Boolean | GetGeom (const Standard_Integer ID, const Standard_Boolean IsElement, TColStd_Array1OfReal &Coords, Standard_Integer &NbNodes, MeshVS_EntityType &Type) const |
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. | |
Standard_Boolean | GetGeomType (const Standard_Integer ID, const Standard_Boolean IsElement, MeshVS_EntityType &Type) const |
This method is similar to GetGeom, but returns only element or node type. This method is provided for a fine performance. | |
Standard_Address | GetAddr (const Standard_Integer ID, const Standard_Boolean IsElement) const |
This method returns by number an address of any entity which represents element or node data structure. | |
virtual Standard_Boolean | GetNodesByElement (const Standard_Integer ID, TColStd_Array1OfInteger &NodeIDs, Standard_Integer &NbNodes) const |
This method returns information about what node this element consist of. | |
const TColStd_PackedMapOfInteger & | GetAllNodes () const |
This method returns map of all nodes the object consist of. | |
const TColStd_PackedMapOfInteger & | GetAllElements () const |
This method returns map of all elements the object consist of. | |
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. |
