KinematicState

Inheritance

    SIObject
       Parameter
           KinematicState

Description

The KinematicState object represents the current pose of a X3DObject object whereas the base pose of an object is represented by the StaticKinematicState property.

The transformation state of the KinematicState object is accessible both through the KinematicState.Transform property and through its ParameterCollection. Both expose the same transformation data, but the KinematicState.Transform is convenient for mathematical manipulation (see XSIMath), while the ParameterCollection exposes the transform as it is shown on the KinematicState property page.
