Computer Graphics Online Test Questions (Computer Graphics FAQs)
1) What is computer graphics?
Computer graphics is a field of computer science which deals with generation of images with the aid of computers.Computer Graphics is mainly used in digital photography, film, video games, cell phone and computer displays, and many specialized applications.
2) Explain 3d transformation in computer graphics?
3D Transformation is the process of manipulating the view of a three-D object with respect to its original position 3-D Transformation is the process of manipulating the view of a three-D object with respect to its original position.
3) What is Scan conversion in computer graphics?
Scan conversion in computer graphics is process of representing continuous graphics objects as a collection of discrete pixels.
4) What is shearing in computer graphics?
Shearing in computer graphics is transformation that changes the shape of object.Shearing can be in one direction or in two directions.It comes handy when you want to skew an object sideways while still keeping the surfaces in perpendicular direction flat.
5) What is the primary use of clipping in computer graphics?
Clipping in computer graphics primarily used to remove objects, lines, or line segments that are outside the viewing pane.
6) What are the components of interactive computer graphics?
The major components of interactive computer graphics are monitor, touch screen, mouse, keyboards or any other device that is used to interact with system using Interactive medium.
7) What is Aspect Ratio?
Aspect ratio is the ratio between the width of an image and the height of an image. It is commonly explained as two numbers separated by a colon, for example- (6:7).
8) What is Reflection?
Reflection in computer graphics is used to emulate reflective objects like mirrors and shiny surfaces. These images can be either on X-axis or Y-axis and the objects can be rotated by 180 degrees.
9) What is critical fusion frequency?
Critical flicker/fusion frequency (CFF) is the transition point for an intermittent light of increasing temporal frequency, where the flickering ceases and the light is perceived as continuous. It is used for moving images.
10) What is a Turtle Graphics Program?
Turtle Graphics program is a library in Python. In computer graphics, turtle graphics are vector graphics using a relative cursor (the "turtle") upon a Cartesian plane. Turtle graphics is a key feature of the Logo programming language.
