[x3d-public] 3D sound with 3D graph.

[John Carlson]

This looks useful:

https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS/Part01/components/picking.html#LinePickSensor

I guess I can make a 3D sound attached to the pickedPoint on a LineSet  I
can also use pickedPoint here:

https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS/Part01/components/picking.html#PointPickSensor

So I guess it’s a matter of routing the pickedPoint to a sound location.

So if I have a Sound.source AudioClip that I can move around by setting
Sound.location to the pickedPoint with a ROUTE.

So really, I don’t need a bunch of sound nodes, but I think I need a bunch
of Picking sensors for all the geometry?  Can someone help here?  Do I only
need one LinePickSensor and one PointPickSensor for the entire scene?  Can
I not rely on TouchSensor, except for announcing the label of a node or
link?  Or do I need TouchSensor to enable and disable sound?

Hopefully I can vibe code some easily, but I’m not opposed to digging in
and doing the work.
