The Volume Visualization System of Synoptic Objects

The volume visualization (volume rendering) is an important instrument in the problems of investigating dynamic of the synoptic objects of atmosphere and ocean. There is a strong demand to perfect the methods/algorithms of rendering in connection with a necessity of quick processing of large data volumes and gain in requirements on the speed and efficiency of 3D data rendering lightening the spatial perception of the synoptic objects. The well-known universally public program systems in this field have a number of disadvantages, particularly: deficient level of interface interactivity and informational content of visualization, and also there is the limited set of the supported data formats and visualization methods.
The advanced implementation of interactive program system of visualization and analysis of synoptic data intended for automation of atmosphere and ocean dynamic investigation is presented in the given work. The new architecture and functionality of the system are described. The program structure of the developed rendering system is given. The methods of rendering of the physical fields of synoptic objects are realized. To increase the calculating capacity of the processed and rendered data we used shader and CUDA technologies of the multiprocessor processing on a basis of graphic processors.
In the new version we realized: the extended functional possibilities for data running; higher performance of data processing at the sacrifice of GPU-parallelism that allows us to do away with binding to the stationary computing equipment; advanced modular structure providing not labor-consuming extension of an algorithmic base without restrictions; modern ergonomic interface providing efficiency and convenience in the researcher operating. The system was tested with the help of model and real data, and it showed the practical efficiency.
