Hey Guys Welcome to CSE STudy247, This page provides you with Computer Graphics MCQ-9
Q.1 The Z-buffer algorithm is primarily used for which of the following?
Hidden line removal
Frame buffer removal
Animation
None
Explanation
The Z-buffer (or depth buffer) algorithm is a common method in 3D graphics used to determine which surfaces are visible and which are hidden.
Q.2 What is considered the primary output device in a standard computer graphics system?
Scanner
Video monitor
Keyboard
None
Explanation
The video monitor is the most fundamental output device used to display processed graphical information to the user.
Q.3 Which type of display technology is best suited for complex graphics systems?
CRT with vector refresh
CRT with raster scan
Plasma panel
LED Display
Explanation
Raster scan monitors are highly suited for modern graphics as they allow for the display of solid colors, patterns, and complex shading.
Q.4 Who is widely recognized as the 'Father of Animation'?
Walt Disney
J. Stuart Blackton
William Horner
None
Explanation
J. Stuart Blackton is considered the father of American animation for creating the first silent films that featured animated sequences.
Q.5 The process of mapping a world window in a coordinate system to a viewport is known as?
Transformation viewing
Viewporting
Clipping window
Screen coordinate system
Explanation
Viewing transformation is the mapping of a part of a world-coordinate scene to device coordinates for display.
Q.6 Gray scale imaging is most commonly used in which scenario?
Monitors that have full color
Monitors where color is not available
Random scan displays
None of the above
Explanation
Gray scale is used in monochrome systems to represent different intensities of light without using actual color data.
Q.7 The maximum number of points that can be displayed without overlap on a CRT is called?
Resolution
Persistence
Attenuation
None of the above
Explanation
Resolution refers to the total number of pixels available on the screen, determining the detail and clarity of the image.
Q.8 The process of changing the position of an object along a straight-line path is called?
Translation
Rotation
Scaling
All of the above
Explanation
Translation is a basic geometric transformation that moves every point of an object by the same distance in a specified direction.
Q.9 Three-dimensional computer graphics became highly effective and mainstream in the late?
1960
1980
1970
None
Explanation
The late 1980s marked a significant era where hardware and software for 3D modeling and rendering became powerful enough for widespread use.
Q.10 Graphics is one of the ________ major key elements in the design of multimedia applications.
5
4
8
None
Explanation
Multimedia design typically consists of 5 core elements: text, images (graphics), audio, video, and animation.
Q.11 'Quake', one of the first fully 3D games to utilize advanced graphics, was released in?
1973
1967
1996
None
Explanation
Quake was released by id Software in 1996 and was a pioneer in using real-time 3D rendering for gaming.
Q.12 A graphics technique used to produce a smooth transformation of one object into another is?
Animation
Morphing
Half tuning
None of the above
Explanation
Morphing is an effect where one image or object is gradually transformed into another through a seamless visual transition.
Q.13 In typical LCD technology, what is the standard refresh rate of the screen?
60 frames/sec
80 frames/sec
30 frames/sec
100 frames/sec
Explanation
A refresh rate of 60Hz (60 frames per second) is the standard for most LCD monitors to ensure flicker-free viewing.
Q.14 In digital graphics, each individual pixel typically consists of ________ basic color components.
Two or three
One or two
Three or four
None
Explanation
Pixels usually consist of three (RGB) or four (RGBA/CMYK) color channels to represent a wide spectrum of colors.
Q.15 Computer graphics models are now essential tools commonly used for making?
Motion Pictures
Music videos
Television shows
All of the above
Explanation
Modern CGI and graphics modeling are utilized across all types of visual media for special effects, backgrounds, and character design.
Q.16 What is the primary purpose of a Display Card (Graphics Card)?
Sending data to input unit
Sending graphics data to output unit
Receiving data from output unit
None
Explanation
The display card processes data from the CPU and sends it to the monitor (output unit) to be displayed as an image.
Q.17 The GIF image format is popular because it is ________ to download or upload over the web.
Faster
Slower
Medium
None
Explanation
GIF is a compressed format that uses a limited color palette, making file sizes small and transmission over the Internet faster.
Q.18 The EPS (Encapsulated PostScript) image file format is used for which of the following?
Vector Graphics
Bitmap
Both A & B
None
Explanation
EPS is a versatile file format that can handle both high-resolution vector paths and bitmap (raster) image data.
Q.19 Which of the following is a recognized algorithm for filling a closed shape with color?
Flood fill
Boundary fill
Both A & B
None
Explanation
Boundary-fill and Flood-fill are the two primary algorithms used in graphics software to color internal areas of shapes.
Q.20 An oblique projection with a specific angle of 45 degrees to the horizontal plane is called?
Cabinet projection
Isometric projection
Cavalier projection
None
Explanation
In Cavalier projection, the receding lines are drawn to the same scale as the front-view lines, usually at a 45-degree angle.
