Hello,
I did a module suite for Netbeans, called X3DV Module Suite.
The X3DV Module Suite is a set of modules to code in X3D, the open standard for interactive and immersive 3D on Internet. With it, you can create virtual worlds in 3D, using the great edition features of Netbeans.

It is free, opensource, LGPL license.
Please comment anything you like, or suggest features. Thank you.
