Detailed Description

This set of classes is a basic implementation of State Chart XML.

It is not complete, nor is it necessary conformant to those parts it implements.

Currently Coin uses SCXML for managing 3D viewer user interaction (the non-model-interaction part) - the examiner navigation mode in layman terms.

The Draft Specification for SCXML is at http://www.w3.org/TR/scxml/.

State Chart XML The ScXML part of Coin is a basic, non-conformant, partial implementation of State Chart XML, based on the W3C Working Draft 16 May 2008 of SCXML http://www.w3.org/TR/2008/WD-scxml-20080516/. The latest version should be at http://www.w3.org/TR/scxml/. Read that document for a basic understanding how SCXML documents should be constructed.

Coin uses SCXML for setting up its navigation systems, to be able to remove hardcoded logic for user navigation and externalize it into XML files. This makes it easy for users to customize the navigation system for their own purposes.

Unsupported Items:

For learning more about how ScXML is implemented and used in Coin, take a look at $COINDIR/scxml/navigation/examiner.xml (or in the Coin source directory, data/scxml/navigation/examiner.xml) for an example of how an SCXML system for camera navigation looks, and look at the source files in src/navigation/ for the C++ counterparts to the same SCXML navigation system.
