Standard_EXPORT XSDRAWSTLVRML_DataSource (const Handle(StlMesh_Mesh)&aMesh)
 Constructor
.
Standard_EXPORT 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_EXPORT 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_EXPORT 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_EXPORT 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.
.
Standard_EXPORT const TColStd_PackedMapOfInteger & GetAllNodes () const
 This method returns map of all nodes the object consist of.
.
Standard_EXPORT const TColStd_PackedMapOfInteger & GetAllElements () const
 This method returns map of all elements the object consist of.
.
virtual Standard_EXPORT 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.
