History 2000, Version 1.0 for Unix, ESA funding 2003, Version 2.3 for Windows&Unix, ESA funding 2009, Version 2.3 for Mac, internal IRF funding 2015  2 programmers involved part-time  Erik Johansson  Fredrik Johansson (currently at LPC2E, Orleans)  Mac/Linux/Windows with Java 1.8 and VTK 6.2  Major change with the recent VTK version, new interfaces, java support has some issues  Java on Mac changed from Apple java 1.6 to Oracle (we target 1.8), “mac java applications” no longer supported, interface to VTK changed  Windows port redone from scratch  Initial beta testing completed  Ready for release in December 2015.

Tasks 1 A) Improve on Usability:  1. Save sessions with all parameters selected on the left column (spacecraft size, labels, footprints, magnetopause, bow shock,..), Done.  2. Improve (magnetic) field line tracing: to be able to switch them to black colours for better visibility in plots, Done.  3. Improve export image with better quality and uses png (and pdf) as export files, PNG done.  4. Add two other lines (text) in the Cluster configuration showing the distances between the four spacecraft, Done.  5. Release a new version of OVT with same functionalities on Mac and PC (December 2015)

Tasks 2 B) Enhanced Planning Support and Orbit Visualization  1. Implement access to orbital data via NASA SSCweb. (Include THEMIS, MMS, and many other SC), Done.  2. use the solar wind dynamic pressure in the JSOC catalogues by default, ??  3. Conjunction analysis tool, that can find magnetic conjunctions between 2 or more s/c (e.g., a tool that returns the times when s/c are within the same magnetic flux-tube; the user could define the max radius of the flux- tube on the magnetic equatorial plane), REJECTED  4. open/closed field lines boundary on the Earth and different colors for open and closed field lines in the magnetosphere REJECTED

Tasks 3 C) Enhanced Science Analysis Support  1. Implement interface to access real solar wind data via AMDA or CDAWEB, Done.  2. foreshock boundary using the solar wind data, Done.  3. Show archive data (CSA) along spacecraft orbit, started  4. 2D and 3D particle tracing tools. REJECTED

Summary Version 3.0 to be released in December 2015 Many more things to do! Should we continue this activity in 2016?
