Explain Two Dimensional Viewing. Reflect the given triangle about X axis. What is the minimum amount of video RAM that the computer must have tosupport the above-mentioned resolution and number of colors? It is the method of incrementally displaying a visual on a CRT.

Write short notes on applying Boolean operations on modeled objects to create new objects 8.

Grzphics is parallel projection? What do you mean by shading of objects? Picture definition is stored in a memory area called the refresh buffer or frame buffer. Brief about select function and shut down functions. Derive the decision parameter for the algorithm and write down the algorithm steps.

Cd2401 detail about Cohen Sutherland line clipping algorithm. That is yellow and orange. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. Differentiate oblique and orthogonal projections. Explain the 16 Disadvantage of it and how to rectify this disadvantage. Answer- In computer graphic, image scaling is the process of resizing a digital image.


Answer- Features of inkjet printers are- 1. What is the difference between impact and non-impact printers? Answer- Following are the applications of computer graphic 1. What do you mean by retracing? What are the steps in animation sequence?

To make a particular window active we simply click in that window using an interactive pointing device. List down the properties of piano curves.

Explain Sutherland-Hodgeman algorithm for polygon 16 7. An average electron beam gives the combination of red and green color. Explain the merits and demerits of Penetration techniques. In the field of entertainment CG methods are now commonly used in making motion pictures.

A shadow Mask CRT has three phosphor color dots at each pixel location. Raster or Bitmap images are resolution dependent because of this its not possible to increase or decrease their size without sacrificing on image quality. What is polygon clipping? Which shading method is faster and easier to calculate? Therefore better print quality is achieved.

It is used to control the operation of the display device by accessing the frame buffer to refresh the screen. Picture information is combined into a composite signal and then separated by the monitor, so the resulting picture quality is still not the best attainable.

Each screen point is referred to as a pixel or pel. Impact printers press formed character faces against an inked ribbon on to the paper. Question-9 What is meant by scan code?

While vector based image are not dependent on resolution. What are the different types of parallel projections? Or we can say that graphics is the representation and manipulation of image data by computer with the help from specialized software and hardware.

Reflect the given triangle about Y-axis. What are the types of reflection of incident light?


Gralhics eight bits constitute a byte, frame-bu ffer sizes of the systems are as follows: What are the types of projection? The Y axis is vertical and Z axis is oriented towards the viewer. How it is differ from Bezier? What is meant by clipping? What is meant by refresh buffer and frame buffer? How are mouse data sent to an OpenGL application? Briefly discuss about logically classification of input devices. Recent electrostatic plotters includes a scan conversion capability. A shadow mask grid is installed just behind the phosphor coated screen.

What do you mean by GUI? What are the disadvantages of DDA algorithm? Give the general expression of Bezier Bernstein polynomial. Obtain a transformation matrix for rotating an object about a specified pivot point.
