Since polygons do not create smooth surfaces, detailed models require a large number of polygons to create an image that looks natural.Īnother technique used to create smooth surfaces relies on a parametric surface, a two-dimensional (2D) surface existing in three dimensions. Other characteristics of the model, such as the color of each vertex and the direction perpendicular to the surface at each vertex, called the normal, also must be specified. Their spatial coordinates represent the points on the surface of the object, called vertices, in the computer.

The surface of an object, such as a sphere, is represented either as a series of curved surfaces or as polygons, usually triangles. The first step in a rendering pipeline is the creation of 3D objects.

However, computer animation almost always uses rendering software because they provide greater control of the images and potentially photo-realistic quality.

Rendering software are very slow, requiring from a few minutes to a full day to render a single image. Hardware rendering can be expensive, but it enables the user to draw up to 60 images per second and to make immediate changes to the image. This graphics pipeline is implemented either with special-purpose 3D graphics microprocessors (hardware) or with computer programs (software). The drawing of 3D scenes, called rendering is usually accomplished using a pipeline or assembly-line approach, in which several program instructions can, at any given time, be executed in various stages on different data. Many uses of computer graphics, such as computer animation, computer-aided design and manufacturing (CAD/CAM), video games, and scientific visualization of data such as magnetic resonance images of internal organs, require drawing three-dimensional (3D) objects on the computer screen. Input parameters consist of conditions that are known at the beginning of a modeling sequence and often have to be estimated. Factors are often represented as sub-models, and interact with each other. The success of computer models is highly dependent on the mathematical representations of systems and on chosen input parameters.įor many systems, graphical or mathematical representations are extremely complex because there are so many factors present. Some types of model involve a computer graphics representation of an object, which can be manipulated on a video display terminal in much the same way that a three-dimensional clay or wood model might be manipulated. When the program is running the mathematical dynamics become analogous to dynamics of the real system. Mathematical equations are constructed that represent functional relationships within a system.

As an example, they can be used to study how changes in levels of sales and prices effect a company's profits.Ī computer model is usually defined in mathematical terms with a computer program. Spreadsheet programs are simple and inexpensive computer models that are widely applicable, especially when accompanied by graphs and charts. The engineer can also study the effects of different materials on physical properties, and the effects of different designs on cost. Not only does the computer aid in the design, it also allows the user to study the response of the designed product to factors such as physical stress. With interactive computer-aided design, engineers draw and redraw designs quickly and inexpensively. Most designs are developed and tested with a computer model. Neural networks, computer approximations of the brain's neural architecture, aid researchers in understanding brain functions. Three-dimensional models of human organs are used to teach anatomy and biology to medical students, with the advantage that the student can manipulate the computer model like a real object, while graphics and animation reveal otherwise hidden information.

In the medical field, computer models are used to develop new drugs and to predict their effects on the body. Those are now used to study economic growth, employment, energy and food resources, population, and housing needs, on a world scale as well as on a local level. A model can also allow an observer to study how the functioning of an entire system can be altered by changing individual components of the system. Computer modeling is the use of computers to model objects and to simulate processes.Ĭomputer models are valuable because they:Īllow a person to study the response of a system to conditions that are not easily or safely applied in a real situation.Ĭan be speed up or slowed down.
