WAEC Computer Studies 2021 Theory — Question 9

Model answer

(i) Interactive Fill Tool: used to create a fill dynamically by using markers in the drawing window and a property bar, to change the angle, midpoint, and colour of an object/image. (ii) Texture Fill Tool: used to apply preset texture fills to objects to create the illusion of a variety of textures, such as water, clouds, and stone. (iii) Envelope Tool: lets the user reshape an object by dragging the nodes or points around the envelope. (iv) Extrude Tool: lets the user apply the illusion of depth to objects — it projects surfaces from an object to give it a 3-dimensional shape/appearance.
