class DataSource from XSDRAWSTLVRML inherits DataSource from MeshVS
|
|
|
|
---Purpose: The sample DataSource for working with STLMesh_Mesh
|
|
|
|
uses
|
|
Mesh from StlMesh,
|
|
|
|
Integer from Standard,
|
|
Boolean from Standard,
|
|
Address from Standard,
|
|
|
|
Array1OfReal from TColStd,
|
|
Array1OfInteger from TColStd,
|
|
SequenceOfInteger from TColStd,
|
|
PackedMapOfInteger from TColStd,
|
|
|
|
EntityType from MeshVS,
|
|
|
|
HArray2OfInteger from TColStd,
|
|
HArray2OfReal from TColStd
|
|
|
|
is
|
|
|
|
Create ( aMesh : Mesh from StlMesh ) returns mutable DataSource from XSDRAWSTLVRML;
|
|
---Purpose: Constructor
|
|
|
|
GetGeom ( me; ID : Integer;
|
|
IsElement : Boolean;
|
|
Coords : out Array1OfReal;
|
|
NbNodes : out Integer;
|
|
Type : out EntityType ) returns Boolean;
|
|
---Purpose: 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.
|
|
|
|
GetGeomType ( me; ID : Integer;
|
|
IsElement : Boolean;
|
|
Type : out EntityType ) returns Boolean;
|
|
---Purpose: This method is similar to GetGeom, but returns only element or node type. This method is provided for
|
|
-- a fine performance.
|
|
|
|
GetAddr ( me; ID : Integer;
|
|
IsElement : Boolean ) returns Address;
|
|
---Purpose: This method returns by number an address of any entity which represents element or node data structure.
|
|
|
|
GetNodesByElement ( me; ID : Integer;
|
|
NodeIDs : out Array1OfInteger from TColStd;
|
|
NbNodes : out Integer ) returns Boolean is redefined;
|
|
---Purpose: This method returns information about what node this element consist of.
|
|
|
|
GetAllNodes ( me ) returns PackedMapOfInteger;
|
|
---C++: return const &
|
|
---Purpose: This method returns map of all nodes the object consist of.
|
|
|
|
GetAllElements ( me ) returns PackedMapOfInteger;
|
|
---C++: return const &
|
|
---Purpose: This method returns map of all elements the object consist of.
|
|
|
|
GetNormal ( me; Id : Integer; Max : Integer;
|
|
nx, ny, nz : out Real ) returns Boolean is redefined virtual;
|
|
---Purpose: 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.
