[x3d-public] Beginner questions

[iam here]

Hi,
I am new to this whole X3D thing, so had a couple of questions:

1) Where does X3D "fit in" in the whole 3D-on-the-web thing? The other
things here include CSS 3D transforms, WebGL (which, as I understand it,
will soon become WebGPU), and just....drawing on a <canvas> with your own
Javascript code, am I correct? So - what exactly *IS* X3D?
2) What is the connection between X3D and glTF? glTF is just a model
format, right? So - is X3D capable of "drawing" glTF models or something,
with Javascript?
3) What is X3D's connection to VRML? Is it the successor? What does that
mean, exactly?
4) Is it possible to make GAMES, or other, interactive 3D, in it? eg. like
Quake or something, when the "up" key is pressed, it has to go *forward* -
can X3D do that??
5) I heard that it's possible to do *character animation* in X3D, ie. you
can tamper with the mesh of say, a man, in Javascript  - how do I do that?
Is there information about this in the Don Brutzman and Leonard Daly book?
(thanks for your help with my previous query, btw, Don! :) )
6) And finally, I've heard about the new Nvidia cards which do Realtime
Raytracing - is it possible to have photoreal graphics inside a web browser
by using X3D?

Ok, that's it. Hope I haven't bugged you too much with my questions :)

Thanks for you guys' help.
