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.

Visualizing and analyzing the data generated by the computational models overwhelms traditional scientific visualization methods.
Compaq expects such clusters to be used for such applications as fraud detection, decision support applications, data warehousing, database loading, computer-aided design, scientific visualization and web search engines.
This ability to extract information and understanding from a large pool of data is the very essence of scientific visualization. Although some three-dimensional (3D) computer displays have been used to enhance the limited capabilities of the human information processing system in data visualization (Wickens, Merwin, & Lin, 1994), others have looked to the new technology of virtual reality (VR) for the solution (Barfield & Furness, 1995; Durlach & Mavor, 1995; Rheingold, 1991).
Information displays have moved past 2D bar charts, line charts and pie charts, and beyond the interactive 3D scatter plots and contour plots of statistical and scientific visualization. It is now possible (on an inexpensive workstation) to build, display and update, in real time, visual scenes composed of abstract 3D geometrical forms.
1.5 Interactive Scientific Visualization of Fluid Flow
Designed for the Apple Macintosh line of computers, Swivel 3D is a three dimensional color graphics program for animation, multimedia presentations, scientific visualization, technical design, and desktop publishing.
Finally, the project will experiment with the application of scientific visualization techniques to represent, geographically and chronologically, the movement of 15th-c.
