Observation

 

The question tested candidates’ knowledge on computer graphics.

 

The expected answer is:

OR
Computer Graphics is the creation of pictures/images/films with the help of a computer.

OR

Computer graphics is the creation, manipulation and storage of geometric objects (modeling) and their images (rendering).

OR

Computer graphics are made up of number of pixels which are the smallest graphical picture or unit represented on the computer screen.
OR
Computer graphics refers to the representation and manipulation of image data by a computer

 

OR
Computer graphics is the various technologies used to create and manipulate images in the form of pixels drawn on the computer /methods for digitally synthesizing and manipulating visual content.

(b)Computer graphic application tools

(i) Interactive fill Tool is used to create a fill dynamically by using markers in the drawing window and property bar to change the angle, midpoint and colour of an object/image.

 

OR
Interactive fill tool allows you to add the same fills to objects as the normal fill tool, but in an interactive way by setting the interactive properties. This is especially useful for fountain fills.
OR
Interactive fill tool is used to apply two colour effect on items
OR
Interactive fill tool is used to apply fountain fills (gradients)

 

(ii)Texture Fill is used to apply preset texture fills to objects in order to create the illusion of variety of textures such as water, clouds and stone.

OR
Texture Fill is used to give an object natural appearance
OR
Texture Fill is used to apply fractal fill

 

(iii)Envelope tool lets you shape an object by dragging the nodes or the points around the envelope.

OR
Envelope tool is used to change the shape of an object by applying and dragging the nodes of an envelope.
OR
Envelope tool allows the user to distort the shape of an object or group of objects

 

(iv)Extrude tool lets the user apply the illusion of depth to objects.

OR
Extrude tool is used to projects surfaces from an object to give it a 3-dimensional shadow/appearance
        OR
Extrude tool is used to apply 3D effect to objects in order to create the illusion of depth
        OR
Extrude tool is used to apply 3D modelling
        OR
        Extrude tool is used to duplicate properties such as points, lines and polygon

 

(c)Tools that are used to create a background that is faded from light blue to white:

 

(i)create background faded from light blue to white;

• Interactive tool
• Fountain fill tool
• Transparency tool

 

(ii)Tools that are used to fill an object with two colours that blend from one to another;

• Interactive tool
• Fountain fill tool
• Two colour pattern fill

                  

It was reported that most of the candidates who attempted this question showed poor knowledge on computer graphics.
