News and Accomplishments

VAPOR Project

Project information is available at: http://www.vapor.ucar.edu

TG GIG PY6 Award:

XD Vis Award:

The final project report was written and submitted to the TACC.

KISTI Award:

John visited KISTI collaborators in Seoul and attended the Korean Supercomputing Conference (KSC). He gave a VAPOR tutorial to to a group from the Korean Meteorological Center, and a talk on VAPOR at KSC. The Koreans indicated their intent to continue funding the VAPOR project for the foreseeable future. Another visitor from KISTI will most likely arrive in the Spring.

Scott also got acquainted with the perl-based VAPOR regression suite, and made some minor usability improvements to the command line translation utilities.

Finally, Scott started evaluating the ESMF re-regridding tools as a possible replacement for our own simplistic and fragile re-gridding code. In addition to finding the ESMF code highly challenging to build, thus far the performance of the ESMF code is an order of magnitude slower than our own. These results are preliminary and further investigation is warranted.

2.3 Development:

We have started work on the vapor 2.3 release in earnest, with a planned RC0 drop targeted for December 15, the end of the KISTI Year Three PoP.  Alan has started work on several planned features, implementing a discrete color mapping and a transfer function in the flow panel.  He has also been fixing bugs in key-framing.

3.x Development:

Alan continued to develop prototype code for Vapor 3.0, based on the functionality we have been discussing in our 3.0 design meetings.  The initial prototype will only support the most basic functionality, such as rendering barbs. Alan has implemented simplified Params and Render libraries to support this functionality, removing all Qt dependence.  This prototype now includes a working barbs renderer.  This work has been put on hold while we work on the 2.3.0 release.

Yannick Polius, Scott's predecessor, has volunteered his time to help out with various rendering related tasks. John and Yannick have been reviewing literature and making plans to prototype a GPU implementation of a ray caster that would support curvilinear and stretched grids (stretched grids are currently supported but the rendering quality can be quite poor if the grids are highly anisotropic).

Miles produced prototype code that demonstrated a method for cleanly interrupting a long running task under Qt.

Education and Outreach:

Scott gave a Vapor demonstration to Andreas Muschinski and his team at the Northwest Research Associates.  They are currently showing interest in how to use Vapor for their research, most importantly a 8192^3 DNS turbulence model; currently the largest turbulence model ever produced.

Scott and John attended IEEE Vis Week in Atlanta.
