(3)Computer simulation “Computer simulation” involves using a computer to simulate an event of some kind. Creating various simulated situations enable results to be realized that are otherwise unattainable using actual theories or experiments. For example, it can be applied to predict damage from building fires, or the effects of global warming on climate. The hardware and software used to perform computer simulations are called a “simulator.” “Interlaced display” refers to a method of dividing the image display operation into two parts and displaying a complete image only when the second part is displayed. It controls flickering when displaying moving images. For this reason, it is used in televisions. Reference Non-interlaced display “Non-interlaced display” refers to a method of displaying a single, complete image all at once. On computer monitors and other display devices that often display static images and letters, the interlaced method tends to produce flickering and bleeding. As a result, most devices use a non-interlaced display. Collage A “collage” is a composite picture created using a computer to combine pictures of scenes and people that were taken separately. Technology element Reference Chapter 9 (4)CAD “CAD” is a system used when designing machines, buildings, electronic circuits, etc. With recent developments in computer graphics, CAD is now used in a variety of situations. Drawings used to be created by hand, but have now become digitalized, making them easier to edit, correct, and render into three-dimensional representations. In addition to floor plans and blueprints for buildings and design plans for automobiles, televisions and other mechanical products, CAD is used to prepare the basic CG data used in media such as commercials and video games.
