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

Wed Feb 12 08:27:59 PST 2025

Hi,

I took a first stab at Displacers in Segments for x3dom and use it now in
the editor:

https://andreasplesch.github.io/Library/Viewer/index.html?url=https://raw.githubusercontent.com/coderextreme/ci2had/refs/heads/main/resources/ManyClocks.x3d

This is experimental and mostly for testing purposes. If there is an
example combining Displacers in both Joints and Segments that would be
interesting as it is not necessarily expected to work.
The experimental implementation is inefficient and expensive as it is
weight_changed event driven. If you activate multiple displacers the frame
rate starts to drop. It probably is not very useful at this point.

Fee free to give it a try, -Andreas
