scientific visualization

Using the computer to display real-world objects that cannot normally be seen, such as the shapes of molecules, air and fluid dynamics and weather patterns. Scientific visualization requires enormous computing resources, and the supercomputer centers and national laboratories throughout the world are always at the forefront of such activity. See visualization.

Visualizing the Structure of Protein
The picture on the left is the x-ray diffraction pattern of an apilopoprotein E3 protein crystal, which plays a major role in cholesterol metabolism. The tiny spots are the x-ray reflections from the crystal, which are used to reconstruct the electron density of atoms (right).

Next Stage - The Structure Model
The colored sticks are the detailed 3-dimensional structure models of the molecule that were fitted into the actual electron density (blue grid-like areas). This stereo image appears 3D when viewed cross-eyed.

The Final Ribbon Model
Using visualization techniques, the overall 3D four-helix bundle structure of the molecule is represented as a ribbon model. The 3D image of this molecule helps researchers better understand it and its interaction with other molecules.

Results are then compared for the same group of students between the situation when they learned with scientific visualizations and when they did not.
Attendees are encouraged to take advantage of this unique opportunity to explore the breakthroughs in scientific visualization and add this as a stop in your SC11 experience.
Use of parallel computational techniques are very well suited for improving the resolution of scientific visualizations, since most images can be easily segmented and the segments individually processed.
It's still something of a technical challenge--it's not easy to do, but high-quality scientific visualization is now within the technical and cost constraints of most research and educational institutions.
In many ways, the major impact of virtual reality technology on scientific visualization is in providing a "real-time" intuitive interface for exploring data while facilitating the use of scientific visualization in the research process.
Recent increases in memory and processing capabilities now allow many to be performed on inexpensive workstations, bringing scientific visualization within reach of a much larger number of environmental researchers.
In some respects, scientific visualization is a generalization of traditional two-dimensional plotting and graphing.
At the same time, visualization experts themselves don't mind showing off a little, especially when their work appears at SIGGRAPH, where scientific visualization shares the stage with dancing raisins and Hollywood dinosaurs.
