(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.

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.

(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.
