[x3d-public] X3D4 Architecture validation and implementation update, with thanks

Tue Dec 22 17:03:10 PST 2020

The point I’m getting at is it’s useful to display X3D using more than one
vendor’s X3D player in the same web page.

I would hope that at some point, vendors could compete on different
features (more granular than a browser or player).   I will start
advocating and trying to design such a thing.   I believe in Java it’s
called a service providers interface.

Would people like to collaborate on such a project?

I do not know how much the SPI has taken off in C# or Java.
