Seven Screens of Mother Earth

Yesterday was a big leap forward for Decision Theater technology. Adam Kubach and Aashish Chaudhary were able to combine ossimPlanet with VR-Juggler to get Earth on all seven screens.


Since ossimPlanet uses OpenSceneGraph to draw, integrating with our existing code-base should be straightforward. Thus, it is likely to become the "platform" on which we build most of our future immersive applications. This includes regional development projects as well as scientific and engineering visualizations that have a geo-spatial component.

Interaction between Turbulence Structures and Suspended Sediment in Rivers

This work actually pre-dates the SERV initiative, but it's a perfect fit for the mission. Mark Schmeeckle and his graduate student, Ryosuke Akahori, are working with the Grand Canyon Monitoring and Research Center to determine how to prevent sandbars in the Colorado River from washing away. Shown below is a screen capture of their simulation of sand particle motion.


Aashish Chaudhary (Lead Programmer) of Decision Theater lead this visualization effort. Other contributors were Jessica Block (Research Scientist) and Perry Miller (Assistant Director). A detailed discussion of the research can be found here.

Decision Theater

Each individual SERV project will be a collaboration between the ASU faculty member(s) who won the award and Decision Theater's scientific visualization experts. If there is a high-performance computing component then the Fulton High Performance Computing group will be engaged as well.

Motivation for SERV

While research in the domain of scientific visualization is well represented at Arizona State University through the Partnership for Research in Spatial Modeling (PRISM), many research efforts in other domains would greatly benefit from state of the practice scientific visualization. This second category – leveraging existing scientific visualization techniques – is much more difficult to fund through outside sources, precisely because it does not advance the art of computer graphics. However, when applied appropriately and effectively, these standard techniques can add value to existing research programs.

In general, scientific visualization can help research efforts in three ways: 1) validating an algorithm or process under development, 2) yielding insight into a data set or experimental sample, and 3) communicating results through compelling images and animations. This last item, outreach, will foster interdisciplinary research by communicating – with a picture – the essence of each researcher’s results to other ASU colleagues.
