Validation of Computer Simulations | Computational Methods

We humans receive our data through the senses of vision, touch, smell, hearing and taste. Scientists have been using mathematical models with great success to reach beyond our senses. Computational methods with the advances in computers have enabled us to apply the mathematical models from the universe at large to protein folding. Once data files are generated, computers can be used to visualize the data in 3D, manipulate the images, ask what if type of questions, and derive valuable information. Computational methods have been applied anywhere from the design of modern airplanes like Boeing 757, to movie special effects with successful results.

Data derived from the computer simulations enabled the Boeing engineers to design the 757.

In the movies it is easy to validate the results of computer simulations. If the audience accepts it as "real", within the context of the movie, it is well done. Special effects have to follow the laws of physics if they are to accepted by the audience as "real".

Wire frame T-Rex represents the data points usually scanned from an actual crafted model.

Texture added to the data points to make it look more realistic.

Data points are manipulated through computations to create the illusion of motion.
