Hello World
Definition: scientific visualization
Using the computer to render real-world patterns such as molecules, fluids and weather. 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
Next Stage - The Structure Model
Final Ribbon Model
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).
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 stage is a 3D four-helix bundle structure of the molecule. Images such as this help researchers better understand molecular interaction. (Images courtesy of Dr. Bernhard Rupp, Lawrence Livermore National Laboratory and Dr. Karl H. Weisgraber, Gladstone Institute of Cardiovascular Disease.)
