About This Release
------------------ 
This is the +0.1.0 upgrade of WorldView 2.0.0 that improves the quality of 
head pose visualisation when viewing data from faceLAB Link.  

Summary of Improvements Version 2.1.0
-------------------------------------

* Fixed avatar head size variability.

* Head pose data is manipulated using quaternions to represent rotation. This 
  avoids unstable results at extreme head angles caused by floating-point 
  precision limits. 
  
* Improved speed and reduced memory usage when loading very large log files.

Summary of Improvements Version 2.0.0
-------------------------------------

* Added recording functionality. Data can now be logged by WorldView
  to a binary file, or over the network by pressing the Record button.

* Added "Stream Mode" selection, for quickly setting whether WorldView is 
  receiving and logging real-time or accurate data.

* Added world model intersections. WorldView independently calculates World-item
  intersections using the source data and the currently loaded world model file.
  This allows for re-recording of faceLAB data with a different world model file
  to the one originally used. Screen intersections are left unchanged from their
  original values

* Windows shell integration. Double-clicking a .fll file in Windows Explorer 
  causes WorldView to launch automatically and begin playing back the file.

* Full-screen mode to view the 3D world display at maximum size.

* Options dialog for configuring recording and display options. These options 
  are saved when WorldView exits and restored the next time it is run.

* Improved the accuracy of the 'playback speed'. 

* Added Experiment Time label to the playback controls window.

* Cleaned up menu items to conform to standard Windows layout.

* Fixed "Next/Previous Keyframe skips to wrong frame" [SP#640]

* Fixed "Deadlock when clicking 'Forward One Frame' during playback [SP#637]

* Fixed "Playback after skipping keyframes starts from beginning of file" [SP#783]

* Fixed "Crash when loading an invalid logfile" [SP#749]

* Numerous user interface improvements and fixes.

Known Issues
------------

* WorldView cannot load files directly from a read-only medium such as a CD-ROM. 
  A workaround is to copy the files to the local hard drive and read them from there.
