Question 2: Who among the following scientists or inventors is regarded as the founding father of computer graphics?
- Ivan Sutherland (Correct answer)
- Nikola Tesla
- Marie Curie
- Ada Lovelace
Correct answer: Ivan Sutherland
Explanation: <br> Computer graphics are credited to Ivan Sutherland as their founding father. In 1963, he created an interactive graphics program called Sketchpad.
Question 3: Which of the following describes computer graphics features?
- Deletion and manipulation of graphical images by computer
- Creation and deletion of images by computer only
- Creation of artificial images by computer only
- Creation and manipulation of graphics by computer (Correct answer)
Correct answer: Creation and manipulation of graphics by computer
Explanation: <br> Computer graphics include creating and modifying graphics (artificial visuals) using computers.
Question 4: Which of the following describes the type of computer graphics?
- Scalar only
- Raster and Vector (Correct answer)
- All of the above
- Raster and Scalar

- Four-dimensional Plane
- Three-dimensional plane
- Two-dimensional plane (Correct answer)
- One-dimensional plane
Correct answer: Two-dimensional plane
Explanation: <br> 2D transformations take place on a two-dimensional plane. The position, size, orientation, and shape of an item can all be changed with the help of transformations.
Question 6: Which of the following is a curve used in computer graphics?
- Implicit Curves
- Bezier Curves
- All of the above (Correct answer)
- Explicit Curves
Correct answer: All of the above
Explanation: <br> There is no limit to the number of points that make up a curve. Each point has two neighbours, except endpoints. The four types of curves are parametric, Bezier, implicit, and explicit.
Question 7: Who used computer graphics for the first time?
- Nicholas Williams
- Ada Lovelace
- Ivan Edward Sutherland
- William Fetter (Correct answer)
Correct answer: William Fetter
