[X3D-Public] Find minimum X3D version for specific nodes?

[Limper, Max]

Dear Don,

thanks again.

I'll go and check out the book you mentioned, we have it here at IGD. I remember that I had a look at several chapters, but I probably skipped the history part at that time ;- )
I hope that we can are able to provide some extensive X3DOM documentation resources for all available nodes ASAP.

Best Regards,
Max

happy to help.  apologies for delayed response.

we did a major revision of the specification documents when going from Version 2.0 (VRML97) to Version 3.0 (X3D).

so literally they are different specifications.  though VRML97 remains active and we can receive/process error reports.

The X3D Immersive Profile is a close approximation to the VRML97 nodes, it adds a few extra.

You can find a comparison of those X3D to VRML nodes as part of the support spreadsheet at

Incidentally a history of VRML/X3D development is found in Chapter 1 of our book _X3D for Web Authors_, the book company agreed that this chapter is also available online free at
