Difference between X3D and X3DV Files

Question

I am wondering what is the difference between an X3D file and an X3DV file.

I am creating a Java application that downloads and displays an X3DV file with the name test.x3dv, and I have several X3D models that I want to download, and I use Xj3D.

However, he only wants to download the X3DV models. So I was wondering what the differences are, so I can change the X3D files that I have for X3DV files.

Answer 1

.x3dis an extension for XML Encoding X3D, while it .x3dvis an extension for Classic X3D Encoding (which is very similar to VRML).
