3d Virtual City

With time the project "Virtual City". With urban simulation UCLA took advantage of this technology, a visual three-dimensional modeling for the development of an integrated urban environment simulation. With a unique system and methodology of computer simulation team is building a virtual model of a real-time urban areas. These models, up to the inscriptions on the walls and curtains in the windows, are constructed by combining photos obtained by aerial photography, with stereometric "representations" streets for a realistic three-dimensional modeling. Another example: until recently, such important projects as the construction of bridges, dams, dams did not take place without any surprises, even in countries with very advanced building technologies. Nowadays, construction companies of many states began to use systems engineering design with the visual display. Modern software engineering graphics are not only committing various building calculations (although it could make and program the previous generation), but also to visualize the ongoing construction processes. Program show not only the possible burden on the individual parts of structures, but also expect various unforeseen events, such as associated with the phenomena of resonance in the construction process. An example from a completely domestic sphere: the company's sale of apartments, as well as design and related repairs were using three-dimensional modeling software to represent the client the most accurate information about the future of the project. Thus the income of these companies began to increase at the expense of saving time spent on useless drawings. The advantage of computer simulation appreciated not only by people associated with real estate and large companies wishing to reduce their costs through the use of modern computer design, as well as automation of the production process. So, IBM offers an automated system design and engineering activities Catia (about this product will be discussed in the next chapter). We will only say that the system will help to create flat drawings, a three-dimensional solid modeling, design complex surfaces, multi-component assembly, chimneys, air tubing, electric current, to calculate the strength. Here is an example of the system: to develop a car Neon, was released in late 1994, the American company Chrysler Motors spent just 31 months, ahead of Japanese companies, has long held the bar at around 36 months. The same system was fully established electronic prototype car Jeep Cherokee, Volvo-960, SAAB-900, WHA, 2110 and the Boeing 777. Incidentally the latter system has saved 15 percent of the total amount of funds - approximately $ 8 million. You long to give examples of these programs, but it is better to consider them from a user perspective, their performance, relevance in various fields.
