X3D-Edit is an open-source Extensible 3D (X3D) Graphics authoring tool
for simple error-free editing, authoring and validation of X3D scenes.
Online at
	https://savage.nps.edu/X3D-Edit

We are happy to announce a new version of X3D-Edit that includes support for
the X3D Followers component, namely Chaser and Damper nodes.  These nodes
help provide superior animation support by rapidly following (Chaser) or
smoothly following (Damper) a target value.  For all such follower animation,
the follower node smoothly tracks between an initialValue field and a
corresponding initialDestination field.

Chasers/damper nodes are provided for simple single-valued and array types:

SFFloat 	ScalarChaser
SFVec2f 	PositionChaser2D, PositionDamper2D
SFVec3f 	PositionChaser, PositionDamper
SFColor 	ColorDamper
SFRotation 	OrientationChaser, OrientationDamper
MFVec3f 	CoordinateDamper

Of note is that there are only a few public Web3D examples available for
testing follower nodes.  I will be working with Herbert Stocker of
BitManagement on adding and testing his examples to the public
Basic examples archive.  Additional contributions will also be welcome.
His Web3D Symposium paper and preliminary examples are online:

Of related interest:  X3D component support for the many components
in X3D version 3.2 are documented for 4 different authoring tools at
http://www.web3d.org/x3d/wiki/index.php/Tool_support_for_X3D_components

Comments and questions welcome, hope you like it.

all the best, Don
