[vtk-developers] change VTK Namespace?

[Jean-Christophe Fillion-Robin]

Hi Martin,

Within VTK all class names starts with the prefix "vtk", that's how all
potential clashes with other toolkit or library is ensured.

Changing all VTK classes from:

class vtkMyClass{
};

to

namespace vtk {
class MyClass{
};
}

would be possible.

Nevertheless, doing so will seriously break backward compatibility. Indeed,
all projects using VTK will have to undergo some serious update.

A an other possibility could be the following, where the namespace is
optional:

#ifdef VTK_USE_NAMESPACE
namespace vtk {
#endif
class vtkMyClass{
};
#ifdef VTK_USE_NAMESPACE
}
#endif

but I dont really see the advantages of doing so.

Thanks
Jc
