XD Vis Award:
KISTI Award:
Scott produced an initial converter for GRIB data that could 1) generate an appropriate .vdf file, and 2) convert our GRIMs files into VDC. The converter was required to store variable metadata (dimensionality, grid type, variable units, etc), as well as the location of each pertinent GRIB message so the data could be looked up at a later point in time. An unpragmatic alternative would be to accumulate the variable data in memory and dump it to VDC after reading the file(s).
After the proof of concept was established, the program was modified to inherit from the DCReader object.
We held a review of the isolines feature and John suggested a number of changes. Alan implemented these.
2.3 Development:
Scott spent some time with the text renderer to resolve two significant bugs that were discovered with it. The first bug was that Windows would crash after generating a large number of isoline annotations. This was resolved by re-drawing a single texture multiple times for a single isoline, as opposed to creating a new texture for each text box that would be drawn.
3.0 Development
Alan and John had a discussion of the new DataMgr design for 3.0 and agreed on a plan to move forward with it.
John continued to refine and document the specification for the new DataMgr v3.0.

Production Visualization Services & Consulting
After Sunni returned to Atlanta from her SiParCS internship, she continued to collaborate with Scott on a submission to this years SC conference. This involved reviewing the WRF forecasts and in-situ data being produced by FRAPPE on a daily basis, and picking data sets with the best aesthetic appeal. After settling on data from two observation periods, Scott went through three iterations of animations produced in VAPOR.
Scott also got the help of Matt Rehme from VETS to apply annotations and intro slides. The animation is currently posted on VAPOR’s media gallery.
Alan and Scott met with Peter Sullivan on August 27 to discuss our initial visualizations of his U, W, and Pressure variables. He seemed pretty excited with our results and talked about what important variable comparisons we should make with our future work. He also asked that we produce visualizations of his temperature variable, Theta.
RFP
John and Dave Hard co-led the Workflow Working Group, which was charged with attempting to better understand CISL user workflows, both in terms of how the resources are used, and why they are used in a particular way. Numerous YS users were identified and interviewed toward this end.
