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

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.

---Purpose: Creates a writer object with default parameters.

|
---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

|
|
-- - shaded
|
|
-- - wireframe
|
|
-- - both shaded and wireframe (default)
