* Web3D Standards Adoption Process

5.c. "Identify at least two independent and interoperable implementations (at least one should be open source)"

Yes, plenty.  We have not taken a recent inventory of features yet, but will be tracking that at

* X3Dv4 Implementations

Our prominent open-source implementations for X3Dv3.3 include FreeWrl, X_ITE, X3DOM, Castle Game Engine.  Soon Xj3D will be back on the table as well.  There are also non-rendering X3Dv4 implementations for Java, JavaScript, Python, conversions and validation.  Not sure about Titania but presumably yes.  X3D-Editv4 is on the horizon. Interestingly everything on this list is open source.

Hoping that FreeWrl developers are keen to keep their record-setting X3D support accomplishments continuing!  8)

All feedback welcome, appreciate your many efforts.
