Question 3

Graphics is one of the major key element in design of multimedia application
A)Five
B)Three
C)Four
D)Eight

Accepted Answer

A

Question 4

Types of computer graphics are
A)Vector and raster
B)Scalar and raster
C)Vector and scalar
D)None of these

Accepted Answer

Vector and raster graphics are the two main types of computer graphics. Vector graphics are composed of paths, while raster graphics are composed of pixels.

Question 5

Which environment has been one of the most accepted tool for computer graphics in business and graphics design studios
A)Graphics
B)Macintosh
C)Quake
D)Multimedia

Accepted Answer

The Macintosh environment has been widely accepted and used in business and graphics design studios due to its user-friendly interface and robust graphic capabilities, making it a preferred choice for professionals in the field.

Question 6

Vector graphics is composed of
A)Pixels
B)Path
C)Palette
D)None of these

Accepted Answer

Vector graphics are composed of paths, which are defined by a start and end point, along with other points, curves, and angles. Unlike raster graphics that are made up of pixels, vector graphics can be scaled indefinitely without losing quality.

Question 7

A palette can be defined as a finite set of colors for managing the
A)Analog images
B)Digital images
C)Both A & B
D)None of these

Accepted Answer

A palette is typically used in the context of digital images to manage and organize colors.

Question 8

Display card is used for the purpose of
A)Sending graphics data to input unit
B)Sending graphics data to output unit
C)Receiving graphics data from output unit
D)None of these

Accepted Answer

Display cards, also known as graphics cards, are primarily used for sending graphics data to the output unit, such as a monitor, to display images and videos.

Question 9

Once a file is saved in JPEG format ,some data is lost
A)Temporarily
B)Permanently
C)Both A & B
D)None of these

Accepted Answer

Saving a file in JPEG format involves a lossy compression technique, which means some original data is lost permanently to reduce the file size.

Question 10

The GIF format is much to be downloaded or uploaded over the www
A)Slower
B)Faster
C)Medium
D)None of these

Accepted Answer

The answer of The GIF format is much to be...

Question 11

The two-dimensional translation equation in the matrix form is
A)P'=P+T
B)P'=P-T
C)P'=P*T
D)P'=p

Accepted Answer

The two-dimensional translation equation in matrix form is represented as P' = P + T, where P' is the translated point, P is the original point, and T is the translation vector. This equation signifies that the new position (P') is the sum of the original position (P) and the translation vector (T), effectively moving the point by the amounts specified in T.

Question 12

The translation distances (dx, dy) is called as
A)Translation vector
B)Shift vector
C)Both a and b
D)Neither a nor b

Accepted Answer

The translation distances (dx, dy) are referred to as both a Translation vector and a Shift vector, making both terms correct.

Question 13

In 2D-translation, a point (x, y) can move to the new position (x', y') by using the equation
A)x'=x+dx and y'=y+dx
B)x'=x+dx and y'=y+dy
C)X'=x+dy and Y'=y+dx
D)X'=x-dx and y'=y- dy

Accepted Answer

The correct equation for 2D translation is x'=x+dx and y'=y+dy, where dx and dy are the distances moved in the x and y directions, respectively. This moves the point (x, y) to a new position (x', y') by adding the respective distances to the original coordinates.

Question 14

The best hidden surface removal algorithm is ?
A)Depth buffer
B)Area subdivision
C)Depends on the application
D)Painters

Accepted Answer

The best hidden surface removal algorithm depends on the application, as different algorithms have their own strengths and are suited to different types of graphics rendering tasks.

Question 15

The surfaces that is blocked or hidden from view in a 3D scene are known as
A)Hidden surface
B)Frame Buffer
C)Quad tree
D)Lost Surface

Accepted Answer

Hidden surfaces are those that are not visible from a particular viewpoint in a 3D scene because they are obscured by other surfaces. The process of determining which surfaces are visible and which are hidden is known as hidden surface determination or visible surface determination.

Question 16

The types of hidden surface removal algorithm are
A)Depth comparison, Z-buffer, back-face removal
B)Scan line algorithm, priority algorithm
C)BSP method, area subdivision method
D)All of these

Accepted Answer

All the mentioned algorithms are types of hidden surface removal algorithms used in computer graphics to determine which surfaces and parts of surfaces are visible from a certain viewpoint. These include depth comparison, Z-buffer, back-face removal, scan line algorithm, priority algorithm, BSP method, and area subdivision method.

Question 17

The transformation in which an object can be shifted to any coordinate position in three dimensional plane are called
A)Translation
B)Scaling
C)Rotation
D)Shearing

Accepted Answer

Translation is the process of moving an object without rotating, resizing, or otherwise deforming it. In a three-dimensional plane, translation shifts the object to a different position without changing its orientation or size.
