Some minor but longstanding action items are to address comments on
the Followers (chasers and dampers) component. Herbert, we need your
feedback please.
Primary points:
- shouldn't there be a ScalarDamper node to correspond to ScalarChaser?
(InstantReality has also implemented this)
- getting consistent browser support for example scenes
http://www.web3d.org/x3d/content/examples/Basic/Followers/
Can we address these points on this Wednesday's X3D conference call?
0800 pacific, 1700 Berlin time. Please attend if possible. TIA.
