Oct 2022 · Question 24

Which of the following is the most appropriate explanation of augmented reality (AR)?

a)By appealing to the five senses through equipment, such as a head-mounted display, a person can experience locations or worlds that do not exist as if they were real.b)By constructing a 3D virtual space that is natural to humans and changing the virtual space in accordance with a person’s movement, he or she can feel as if he or she were in that place.c)By seamlessly interweaving computer-generated information with the physical world, the viewer can perceive it as an immersive aspect of the real environment.d)By viewing a video recorded in the past, the viewer can feel as if he or she were in that era and at that location.

Apr 2021 · Question 24

Which of the following explains a drawing software?

a)It can create a picture on a screen using the mouse as a brush that can be saved to a bitmap image file.b)It can create a scenario-based content by editing and arranging several materials, such as text, images, video, and sound.c)It can create a simple movie from a series of still images by gradually changing the differences among images.d)It can create vector graphics composed of lines and curves defined mathematically with geometric characteristics that can then be transformed or combined.

Oct 2021 · Question 24

Which of the following is an explanation of clipping in 3D graphics processing?

a)It is a process that applies shading to the surface of an object for a more 3D appearance.b)It is a process that defines a window within the image display area, removes the area outside the window, and cuts out the section visible within the window.c)It is a process that is performed in the last phase of CG video production and visualizes object data so that it can be rendered on the screen.d)It is a process to hide the jaggies that occur near the edge of a shape because of the limited number of pixels on the screen.
