News and Accomplishments
VAPOR Project
Project information is available at: http://www.vapor.ucar.edu
TG GIG PY6 Award:
XD Vis Award:
- Extensions were made to the ShaderMgr to better manager OpenGL context information across the entire vaporgui application.
KISTI Award:
- Alan completed command-line programs roms2vdf and romsvdfcreate to read and convert ROMS data as requested by our KISTI partners. Justin Small at NCAR was instrumental in showing us how to remap the ROMS data to a lat/lon/depth grid. Katherine Hedstrom, a ROMS developer at the University of Alaska, provided lots of general information about the ROMS model.
- We wrote Python scripts to enable calculation and visualization of ROMS and MOM flow data on lat/lon grids.
Development:
We are starting to prepare for the next release of VAPOR, version 2.2. A release candidate is in the works, and the hope is to make it available to friendly users in early October.
- John implemented Tiled Map class object that is compatible with the schemes used by Google Maps, Microsoft Bing, and the open source Tiled Map service. In the short term the new capability will allow us to crop maps to arbitrary rectangular lat-long coordinates, and will handle periodicity of longitude. Longer term we will be in a better position to support tiled maps produced by other services (e.g. Google Maps)
- A number of memory leaks were fixed in the VDC2 data translator
- Missing data values were not handled correctly for terrain following grids.
- Regression testing and bug fixing kicked off in earnest and a number of minor bugs were found and fixed
- The dozen or so 3rd party libraries that VAPOR depends on were updated to the most recent stable versions. Builds were performed for Linux and Mac, 64bit. 32bit and Windows remain to be done.
Administrative:
- CISLAR reports were written on VAPOR, Large Data Visualization, and VAPOR training
- POPPR reports were submitted on VAPOR and Training.
Education and Outreach:
- A number of animations were assembled for use at the NWSC grand opening, and the SC12 research exhibit.
Software Research Projects
Feature Tracking:
Climate data compression:
ASD Support
- Alan met with Baylor Fox-Kemper and Peter Hamlington in preparation for their ASD project that examines the turbulence in ocean water induced by contact with the atmosphere. We increased the temporal resolution by a factor of 100 and were able to nicely visualize the moving waves at the surface. We plan to extract the appropriate data during the ASD simulation to capture an animation of these waves.
Production Visualization Services & Consulting
- Janice Coen created VAPOR visualizations of two wildfires using VAPOR. Alan worked with her, using the new VAPOR animation control capability, to animate the viewpoint so that one can follow the important features of the fire as it moves and evolves.
