I'm making an app in Java that loads and displays X3DV files, I have a testing class that loads a file called test.x3dv which is a rotating red cube, and I'm using Xj3D to import it into Java. However, I have about 90 different X3D files that I want to display and it wont load in the test class as they aren't X3DV files. I was wondering if there's a way of changing X3D files into X3DV files.
