Yes looks good. Web3d covid-19 response: create some new nodes for it.

UserBody extension

- interesting and reminded me a bit of the 3Dmouse/spacemouse

 https://www.3dconnexion.com/products/spacemouse.html

issue: if it's 3rd person, it can be hard to follow, for example

https://www.youtube.com/watch?v=UC6suYVm60s
- the soccer players are wearing HMDs. The HMDs show the soccer field from
above - that's all they see. That's like a 3rd person shooter.
As they look down on the field from 3rd person, they have to figure out how
to move from first-person.


To avoid that 3rd-person problem while decoupling the viewpiont from
UserBody ray-casting and collision,  UserBody can still be coupled to the
avatar travel/pose -like your arms are attached to your body- so move with
the avatar / relative to the avatar. That might not be a requirement of any
UserBody nodes, but might be how they are easiest to use.


Maybe a first step is to develop some emulators / simulators for various
new types of input devices to control UserBody.

Multitouch x3d
In freewrl I have WM_TOUCH windows 7-10 style independent (non-gesture)
touch events being handled independently / non-gesture-wise in windows
version, and in such a way you can drag multiple drag sensors
simultaneously - a touchID is associated with each drag during its life
(and touchIDs can be recycled).

Multitouch Emulation for X3D
 Freewrl -all platforms- has a built-in multi-touch emulator (current
develop branch commandline --touchtype 1 or options panel),
- to use, with mouse, RMB-right-mouse-button-click to create a new
touch/drag LMB to drag it, and another RMB to delete it. Can create several
and have them in various drag states using regular mouse.

General Multitouch emulation for windows 10
for win10 I developed a touchServer and touchSender for emulating a
multi-touch device on a 2nd computer and the server via tcp injects the
touches into the desktop for any application

Multi-touch application
I had developed a play game for kids for a (now obsolete) kids
mutlitouch table

https://support.smarttech.com/hardware/other-hardware/tables

for organic chemistry - assembling carbon atom chains - not in x3d, they
had their own API - and could have up to 16 simaltaneous touches/drags.
