Interface ScalarDamper

All Superinterfaces:
X3DChildNode, X3DDamperNode, X3DFollowerNode, X3DNode
All Known Implementing Classes:
ScalarDamper
public interface ScalarDamper extends X3DDamperNode
ScalarDamper generates a series of floating-point values that progressively change from initial value to destination value.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. X3D node tooltip: (X3D version 3.3 or later) [X3DDamperNode] ScalarDamper generates a series of floating-point values that progressively change from initial value to destination value. Hint: ROUTE value_changed output events to an interpolator node's set_fraction field, for example. *


Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
