class MaterialTool from XCAFDoc inherits Attribute from TDF
---Purpose: Provides tools to store and retrieve attributes (materials)
-- of TopoDS_Shape in and from TDocStd_Document
-- A Document is intended to hold different
-- attributes of ONE shape and it's sub-shapes
uses
Shape from TopoDS,
Label from TDF,
LabelSequence from TDF,
Document from TDocStd,
ShapeTool from XCAFDoc,
RelocationTable from TDF,
HAsciiString from TCollection
is
Create returns MaterialTool from XCAFDoc;
Set (myclass; L : Label from TDF) returns MaterialTool from XCAFDoc;
---Purpose: Creates (if not exist) MaterialTool.
GetID (myclass)
---C++: return const &
returns GUID from Standard;
---API: General structure
BaseLabel(me) returns Label from TDF;
---Purpose: returns the label under which colors are stored
ShapeTool (me: mutable) returns ShapeTool from XCAFDoc;
---Purpose: Returns internal XCAFDoc_ShapeTool tool
---C++: return const &
-- Methods for Material:
IsMaterial (me; lab: Label from TDF) returns Boolean;
---Purpose: Returns True if label belongs to a material table and
-- is a Material definition
GetMaterialLabels (me; Labels: out LabelSequence from TDF);
---Purpose: Returns a sequence of materials currently stored
-- in the material table
AddMaterial (me; aName : HAsciiString from TCollection;
aDescription : HAsciiString from TCollection;
aDensity : Real from Standard;
aDensName : HAsciiString from TCollection;
aDensValType : HAsciiString from TCollection)
returns Label from TDF;
---Purpose: Adds a Material definition to a table and returns its label
SetMaterial (me; L: Label from TDF;
MatL: Label from TDF);
---Purpose: Sets a link with GUID
SetMaterial (me; L: Label from TDF; aName : HAsciiString from TCollection;
aDescription : HAsciiString from TCollection;
aDensity : Real from Standard;
aDensName : HAsciiString from TCollection;
aDensValType : HAsciiString from TCollection);
---Purpose: Sets a link with GUID
-- Adds a Material as necessary
GetMaterial (me; MatL: Label from TDF; aName : out HAsciiString from TCollection;
aDescription : out HAsciiString from TCollection;
aDensity : out Real from Standard;
aDensName : out HAsciiString from TCollection;
aDensValType : out HAsciiString from TCollection) returns Boolean;
---Purpose: Returns Material assigned to <MatL>
-- Returns False if no such Material is assigned
GetDensityForShape (myclass; ShapeL: Label from TDF) returns Real from Standard;
---Purpose: Find referred material and return density from it
-- if no material --> return 0
ID (me)
---C++: return const &
returns GUID from Standard;
Restore (me: mutable; with : Attribute from TDF);
NewEmpty (me)
returns mutable Attribute from TDF;
Paste (me; into : mutable Attribute from TDF;
RT : mutable RelocationTable from TDF);
fields
myShapeTool: ShapeTool from XCAFDoc;
end MaterialTool;
