class Writer from VrmlAPI
---Purpose: Creates and writes VRML files from Open
-- CASCADE shapes. A VRML file can be written to
-- an existing VRML file or to a new one.

is
Create returns Writer from VrmlAPI;
---Purpose: Creates a writer object with default parameters.
ResetToDefaults(me : in out);
---Purpose: Resets all parameters (representation, deflection)
-- to their default values..
Drawer(me) returns Drawer from VrmlConverter;
---Purpose: Returns drawer object
SetDeflection(me : in out; aDef : Real from Standard);
---Purpose: Sets the deflection aDef of
-- the mesh algorithm which is used to compute the shaded
-- representation of the translated shape. The default
-- value is -1. When the deflection value is less than
-- 0, the deflection is calculated from the relative
-- size of the shaped.
SetRepresentation(me : in out; aRep : RepresentationOfShape from VrmlAPI);
---Purpose: Sets the representation of the
-- shape aRep which is written to the VRML file. The three options are :
-- - shaded
-- - wireframe
-- - both shaded and wireframe (default)
-- defined through the VrmlAPI_RepresentationOfShape enumeration.
SetTransparencyToMaterial(me : in out; aMaterial : in out Material from Vrml;
aTransparency : Real from Standard);
---Purpose: Set transparency to given material
SetShininessToMaterial(me : in out; aMaterial : in out Material from Vrml;
aShininess : Real from Standard);
SetAmbientColorToMaterial(me : in out ; aMaterial : in out Material from Vrml;
Color : HArray1OfColor from Quantity);
SetDiffuseColorToMaterial(me : in out ; aMaterial : in out Material from Vrml;
Color : HArray1OfColor from Quantity);
SetSpecularColorToMaterial(me : in out; aMaterial : in out Material from Vrml;
Color : HArray1OfColor from Quantity);
SetEmissiveColorToMaterial(me : in out ; aMaterial : in out Material from Vrml;
Color : HArray1OfColor from Quantity);
----------------- Returns fields of class --------------------------------------
GetRepresentation(me) returns RepresentationOfShape from VrmlAPI;
---Purpose: Returns the representation of the shape which is
-- written to the VRML file. Types of representation are set through the
-- VrmlAPI_RepresentationOfShape enumeration.
GetFrontMaterial(me) returns Material from Vrml;
GetPointsMaterial(me) returns Material from Vrml;
GetUisoMaterial(me) returns Material from Vrml;
GetVisoMaterial(me) returns Material from Vrml;
GetLineMaterial(me) returns Material from Vrml;
GetWireMaterial(me) returns Material from Vrml;
GetFreeBoundsMaterial(me) returns Material from Vrml;
GetUnfreeBoundsMaterial(me) returns Material from Vrml;
Write(me; aShape : Shape from TopoDS; aFile : CString from Standard);
---Purpose: Converts the shape aShape to
-- VRML format and writes it to the file identified by aFile.
