Since VRML is no longer under development, and has been superseded by X3D if you have VRML files you want to work with, your options are a little bit limited. Some CAD applications, including Autodesk 3DS, can import and work with VRML objects. In addition, Cortona3D Viewer, is an application that is free for non-commercial use, and works as a VRML plugin for popular browsers and office applications, allowing you to view VRML objects in common applications.
