scientific visualization
Process of graphically displaying real or simulated scientific data. It is a vital procedure in the creative realization of scientific ideas, particularly in computer science. Basic visualization techniques include surface rendering, volume rendering, and animation. High-performance workstations or supercomputers are used to show simulations, and high-level programming languages are being developed to support visualization programming. Scientific visualization has applications in biology, business, chemistry, computer science, education, engineering, and medicine.
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.

| 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.
