(a)(i) Define computer graphics.
(ii) List two applications of computer graphics in advertising.
(b) Give one use of the following computer graphics application tools;
(i) Interactive Fill Tool (ii) Texture Fill Tool (iii) Envelops Tool (iv) Extrude Tool
(c) Name one Fill Tool in computer graphic application which is needed to (i) create a background that is faded from light blue to white (ii) fill an object with two colours that blend from one to another.
Explanation
(a) Computer graphics;
(i) Computer graphics are pictures and images/films created using computers. It refers to computer generated image data created with help from specialized graphical hardware and software. OR Computer Graphics is the creation of pictures/ímages/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 is an art of drawing pictures, lines, charts and other graphical images with the help of installed specialized programs on a computer/applications on a computer. 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 refer to the representation and manipulation of image data by a computer screen. OR Computer graphics is the various technologies used to create and manipulate images in form of pixel drawn on the computer/methods for digitally synthesizing and manipulating visual content,
(ii) Specific application areas of graphics in advertising; (1) Animation/Motion pictures (2) Business card (3) Branding (4) Billboards (5) Flex creation (6) Posters (7) Modelling/Design (8) Digital marketing (9) Pitching for project (10) Print media ads (11) Tv commercials (12) Banner (13) Logo design (14) Letter-head (15) Presentation (16) Postcards (17) Info graphics (18) Brochure (19) Vehicle wraps (20) Signature and trade show display (21) Email marketing templates
(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) Envelop tool lets you shape an object by dragging the nodes or the points around the envelop. OR Envelop tool is used to change the shape of an object by applying and dragging the nodes of an envelop. OR Envelop 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 project surfaces from an object to give it a 3-dimensional shadow/appearance OR Extrude tool is used to a apply a 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; (a) Interactive tool (b) Fountain fill tool (c) Transparency tool
(ii) Fill an object with two colours that blend form one to another; (a) Interactive tool (b) Fountain fill tool (c) Two colour pattern fill
