[x3d-public] Turning on and off simultaneous animations individually

Sat Dec 7 14:56:36 PST 2024

Joe suggested using an event hierarchy, and then only adding and removing
one event per facial expression as you turn them on an off.

Everything is visible here, it’s about controlling all animations (and any
subset) with only a single TimeSensor.

Putting sensors in a Switch is another possibility, but the goal is to have
a single sensor, so we can have several facial expressions (any combination
potentially) running on the same sensor.

My ideal was to have several Switches, one per facial expression.  Then
have a Group with ROUTEs and one without.  I’m guessing that doesn’t agree
with the specification.

You’re welcome to see what we have:

Just realize that we want to toggle on and off  menu items in groups.

Note that the image is copyright HP, so use care when copying.  You
probably have it from before I knew about the copyright.

Fun stuff!
