Hello students in this page provide you with Computer Graphics MCQ-3
Q.1 Who is considered the father of animation?
Walt Disney
J. Stuart Blackton
William Horner
J.A. Ferdinand Plateau
Explanation
J. Stuart Blackton is considered the father of American animation for creating the first silent film that included animated sequences.
Q.2 What does the acronym CRT stand for in display technology?
Cathode Red Tube
Carbon Ray Tube
Cathode Ray Tube
None of these
Explanation
CRT stands for Cathode Ray Tube, a vacuum tube used as a display screen in older monitors and televisions.
Q.3 A Random scan system (vector display) uses which of the following to draw images?
Electrical Beam
Electron Beam
Electron line
None of these
Explanation
Random scan systems direct an electron beam directly to the specific parts of the screen where an image is to be drawn, rather than scanning the whole screen.
Q.4 Which of the following are recognized two-dimensional color models?
RGB and CMKY
RBG and CYMK
RGB and CMYK
None of these
Explanation
RGB (Red, Green, Blue) is an additive color model for displays, and CMYK (Cyan, Magenta, Yellow, Black) is a subtractive model for printing.
Q.5 Which type of animation is specifically used to animate objects that are smaller than life size?
Immersive
Clay motion
Stop motion
Augmented
Explanation
Stop motion is a technique used to animate physical objects by moving them in small increments and capturing them frame by frame.
Q.6 Which of the following is an INCORRECT statement regarding the DDA line algorithm?
Read end points of line to start the process
Plot function plots the values of X & Y Coordinates
Sign function makes the algorithm work only in two quadrants
None of these
Explanation
The sign function in DDA helps the algorithm handle lines in all four quadrants by determining the direction of increments.
Q.7 Translate the polygon A(2,5), B(7,10), C(10,2) by 3 units in X and 4 units in Y. What are the new coordinates?
A'(10,14), B'(5,8), C'(13,6)
A'(5,9), B'(10,14), C'(13,6)
A'(5,9), B'(7,8), C'(13,6)
None of these
Explanation
Translation is calculated as x’ = x + tx and y’ = y + ty. So: (2+3, 5+4)=(5,9), (7+3, 10+4)=(10,14), (10+3, 2+4)=(13,6).
Q.8 What does the acronym LCD stand for?
Liquid Crystal Display
Liquid Crystal Dot
Line Crystal Display
None of these
Explanation
LCD stands for Liquid Crystal Display, which uses the light-modulating properties of liquid crystals to display images.
Q.9 For which of the following applications is the RGB color model primarily used?
Printing
Painting
Computer display
None of these
Explanation
The RGB (Red, Green, Blue) model is an additive color model used primarily for electronic displays like monitors and TVs.
Q.10 How many primary types of video compression are there generally categorized?
2
3
4
5
Explanation
Video compression is generally categorized into two main types: Lossy and Lossless.
Q.11 Which of the following is a valid application of computer graphics?
Office Automation
Desktop Publishing
Art and Commerce
All of these
Explanation
Computer graphics are used across various fields including office tools, publishing, creative arts, and business presentations.
Q.12 A pixel is defined as the ________ addressable element on a display screen.
Largest
Smallest
Both A & B
None of these
Explanation
A pixel (picture element) is the smallest physical point in a raster image and the smallest addressable unit on a display.
Q.13 Which component contains an internal digital representation of the image currently on screen?
Frame Buffer
Lab Buffer
Pixel Buffer
None of these
Explanation
The frame buffer is a specialized portion of RAM that stores the bitmap or pixel data for a complete frame of a video display.
Q.14 The intersection of the three primary colors (Red, Green, and Blue) at maximum intensity produces?
White color
Black color
Magenta color
Red color
Explanation
In the additive color model (RGB), combining the three primary colors at full intensity results in white.
Q.15 What is the most commonly used boundary representation for a 3-D graphics object?
Data polygon
Surface polygon
System polygon
None of these
Explanation
Surface polygons are the standard way to represent 3D objects by defining their boundaries as a mesh of connected flat surfaces.
Q.16 In perspective projection, what is the intersection point of visual rays with the Picture Plane (PPP) called?
Penetration point
Piercing point
Exit point
Vanishing point
Explanation
The piercing point is where a visual ray from the object passes through the projection plane to reach the eye.
Q.17 What does the acronym SVGA stand for?
Super Video Graphics Array
Super Video Graph Array
Super Video Graphics Array
None of these
Explanation
SVGA stands for Super Video Graphics Array, a standard for high-resolution computer displays.
Q.18 In which year was the SVGA (Super Video Graphics Array) standard introduced?
1985
1987
1990
None of these
Explanation
The SVGA standard was introduced in 1987 to provide higher resolutions and more colors than the standard VGA.
Q.19 In a black-and-white display system, each single bit in the frame buffer represents?
1 color
2 colors
None of these
Explanation
A single bit can represent two states (0 or 1), which translates to two colors (usually black and white).
Q.20 Which specific vertical projection plane is used to obtain an object's perspective view?
Orthographic plane
Vertical plane
Perspective plane
Horizontal plane
Explanation
The perspective plane (or picture plane) is the surface upon which the 3D scene is projected to create a perspective image.
