1) Version of VRML format is added to VrmlAPI_Writer::Write() and VrmlAPI::Write() to allow use the both versions of the VRML by one writer. 2) Unification of the command to write VRML of both versions. Now "writevrml" command can write VRLM files of v1.0 and v2.0, with wireframe/shaded/both representations. Parameter "Deflection" was removed (next commit will remove meshing, so parameter will be useless). 3) Meshing is removed from writers of both (v1.0 and v2.0) versions. Shaded representation is skipped in case when a mesh does not exist. Wireframe representation checks the existence of a mesh before. If the mesh exists, a deflected edges are taken from the mesh, otherwise - are generated with the default deflection. 4) Drawing of redundant edges is removed in wireframe representation of VRML version 1.0 (a grid on non-plane surfaces does not match a real edges of TopoDS_Shape and does not match representation in version 2.0). Test case for issue CR25279

|
|
---Purpose: Identifies the representation of the shape written
|
|
-- to a VRML file. The available options are :
|
|
-- - VrmlAPI_ShadedRepresentation :
|
|
-- the shape is translated with a shaded representation.
|
|
-- - VrmlAPI_WireFrameRepresentation :
|
|
-- the shape is translated with a wireframe representation.
|
|
-- - VrmlAPI_BothRepresentation : the shape is translated
|
|
-- to VRML format with both representations : shaded and
|
|
-- wireframe. This is the default option.

---Purpose: With help of this class user can change parameters of writing.
|
|
|
|
Write(aShape: Shape from TopoDS; aFileName: CString from Standard; aVersion: Integer = 2);
|
|
---Purpose: Converts the shape aShape to VRML format of the passed version and writes it
|
|
-- to the file identified by aFileName using default parameters.
