What is a computer simulation?
Computer simulation has three meanings. Computer simulation can refer to a computer program that simulates an abstract model so that it can be studied and analyzed. It can also refer to a 3D computer graphic model created to represent a three -dimensional object using specialized software. Finally, computer simulation can refer to practice called emulation in which the function of a particular system is reproduced on the second system. Computer simulation of this type creates a sampling of representative results or sequences of events in situations in which playing all possible consequences of the model is unbearable and models can be more or less abstract. Computer models are used in biology, chemistry and physics, as well as economics and psychology. Uterus compmodels are categorized on the basis of a set of four variables. Are they stochastic or deterministic? Standed or dynamic? continuous or discreet? Local or distributed?
Computer simulations in the form of 3D models are used in healthcare, science, architecture and the most popular pictures, computer games and video games. Most 3D models receive one of two approaches. On the one hand, they can display the object as fixed and define it according to its volume. The alternative is to show the boundary or shell of the object. This is a predominant model for games and film.
3D models can be created in different ways. Like some books that learn, they can be based solely on very basic geometric shapes. While books of drawings use circles, squares, triangles and other 2D models, for example, computer modeling would use balls, cubes and pyramids. This style of modeling is called primitive because it is limited to the use of primitive or basic shapes.
There are three other types of model creation. One of them is nurbs (uneven rational B-SPLINE), who came from two engineers who worked for French car manufacturers, Pierre Bézier and Paul de Casteljau. Bézier's choice to publish his work resulted in his name closely associated with curves. NURBS are used in computer -supported design (CAD) programs, as well as programs for production, engineering and animation.
Spline and patches are similar to NURBS, and the surface is defined by curved lines. Polygonal modeling forms a polygonal net using line segments to connect the peaks. They are used in many 3D models, but may approximately curved surfaces because each polygon is flat.
The type of computer simulation known as emulation can allow one device to imitate another. This is useful, for example, if a specific peripheral brand has the dominance of the market and peripherals from other brands can imitate dominant devices for easy use. Software emulators to start Apple software on other platformsWindows Mac and software on Apple Macintosh computers are another use for this type of modeling.
