Abstract
A method and system for providing access to and control of parameters within a scenegraph includes redefining components or nodes' semantic within a scenegraph. The set of components or nodes (depending on the scenegraph structure) are required to enable access from the Application User Interface to selected scenegraph information. In one embodiment, a user interface is generated for controlling the scenegraph parameters. In addition, constraints can be implemented that allow or disallow access to certain scenegraph parameters and restrict their range of values.

A system for controlling a scenegraph during rendering comprising:
- means for rendering an existing scenegraph;
- means for identifying a subset of elements within a scenegraph for providing additional user control not provided by a scenegraph structure of the scenegraph;
- means for generating a user interface for controlling at least one parameter of the identified elements, including creating a new graphical interface widget for controlling the at least one parameter through the user interface and creating a name for the parameter having a simplified description that is different than an identifier in the scenegraph;
- and
- means for linking control information from the user interface to the scenegraph structure.
An apparatus for controlling a scenegraph during rendering comprising:
- memory;
- and
- at least one processor coupled to the memory and configured to:
- render a scenegraph;
- identify a subset of elements within the scenegraph for providing additional user control not provided by a scenegraph structure of the scenegraph;
- generate a user interface for controlling at least one parameter of the identified elements, including creating a new graphical interface widget for controlling the at least one parameter through the user interface and creating a name for the parameter having a simplified description that is different than an identifier in the scenegraph;
- and
- link control information from the user interface to the scenegraph structure.
