Computer graphics are graphics created by computers and, more generally, the A defined common extension to the X Window System allows an OpenGL client on one.

Some system has multiple bits per pixel, the frame buffer is often referred to as pixel map. Write the types of clipping?

Point clipping, line clipping, area clipping, text clipping and curve clipping. What is meant by scan code?

45 TOP Computer Graphics VIVA Questions and Answers

When a key is pressed on the keyboard, the keyboard controller places a code carry to the key pressed into a part of the memory called as the keyboard buffer. This code is called as the scan code.

List out the merits and demerits of Penetration techniques? The merits and demerits of the Penetration techniques areas follows. It is an inexpensive technique. It has only four colors.

The quality of the picture is not good when it is compared to other techniques. It can display color scans in monitors. Poor limitation etc. List out the merits and demerits of DVST? The merits and demerits of direct view storage tubes[DVST] are as follows.

It has a flat screen. Refreshing of screen is not required. Selective or part erasing of screen is not possible. It has poor contrast Performance is inferior to the refresh CRT. What do you mean by emissive and non-emissivedisplays? The emissive display converts electrical energy into lightenergy. The plasma panels, thin film electro-luminescent displays are the examples. The Non-emissive are optical effects to convert the sunlightor light from any other source to graphic form.

Liquid crystal display is an example List out the merits and demerits of Plasma paneldisplay? Refreshing is not required. Produce a very steady image free of Flicker. Less bulky than a CRT. Poor resolution of up to 60 d. It requires complex addressing and wiring.

It is costlier than CRT. What is persistence? The time it takes the emitted light from the screen to decay one tenth of its original intensity is called as persistence. What is Aspect ratio?

The ratio of vertical points to the horizontal points necessary to produce length of lines in both directions of the screen is called the Aspect ratio.

What is the difference between impact and non-impactprinters? Impact printer press formed character faces against an inked ribbon on to the paper. A line printer and dot-matrix printer are examples. Non-impact printer and plotters use Laser techniques,inkjet sprays, Xerographic process, electrostatic method sand electrothermal methods to get images onto the papers.

Define pixel?

Pixel is shortened forms of picture element. Each screen point is referred to as pixel or pixel. What is frame buffer? Picture definition is stored in a memory area called frame buffer or refresh buffer. Where the video controller is used?

A special purpose processor, which is used to control the operation of the display device, is known as video controller or display controller. What is run length encoding? Run length encoding is a compression technique used to store the intensity values in the frame buffer, which store search scan line as a set of integer pairs.

One number each pair indicates an intensity value, and second number specifies the number of adjacent pixels on the scan line that are to have that intensity value. What is point in the computer graphics system? Write short notes on lines? Define Circle? Circle is defined by its center xc, yc and its radius in user coordinate units. What are the various attributes of a line? The line type, width and color are the attributes of the line. The line type include solid line, dashed lines, and dotted lines.

What is anti aliasing? The process of adjusting intensities of the pixels along the line to minimize the effect of aliasing is called anti aliasing. Question-4 Write the difference between vector and raster graphics?

Answer-Following are the differences between vector and raster graphics- 1.

CG Viva+questions+&ANSWERS

Raster or Bitmap images are resolution dependent because of this its not possible to increase or decrease their size without sacrificing on image quality. While vector based image are not dependent on resolution.

The size of vector image image can be increased or decreased without affecting image quality. Raster or bitmap images are always rectangular in shape, Vector image, however, can have any shape. Question-5 What is scaling in computer graphics? Answer- In computer graphic, image scaling is the process of resizing a digital image. Question-6 What are the hardware devices used for computer graphics? Question-7 What are the features of inkjet printers?

Answer- Features of inkjet printers are- 1. They can print 2 to 4 pages per minute. Therefor better print quality is achieved. The operating cost is very low. The only part that requires replacement is ink cartridge. Four colors cyan, yellow, magenta, black are available. Question-8 What are the advantages of electrostatic plotters? Answer- Following are the advantages of electrostatic plotters- 1.

They are faster then pen plotters and very high quality printers. Recent electrostatic plotters includes a scan conversion capability.

They make multiple passes over the paper to plot color picture. Question-9 What is meant by scan code? Answer- When a key is pressed on the keyboard, the keyboard controller places a code carry to the key pressed in to the part of the memory called as the keyboard buffer.

This code is called as scan code. Question Define Random and Raster scan displays? Answer- Random scan is a method in which display is made by electronic beam, which is directed only to the points or parts of the screen where picture is to be drawn. The Raster scan system is a scanning technique in which the electron sweep from top to bottom and from left to right.

The intensity is turned on or off to light and un-light the pixel. Some Important Questions computer science engineering Graphic Technologies. Sample Paper For Computer Graphics. You can earn additional bucks easily, search on youtube for: Consider a ray passing through a sphere.

Find the point on this ray closet to the center of the sphere. How can you use this result to intersection testing?. Prove that rotation followed by translation is not same as translation followed by rotation in three dimension.

I want to do my project on Clone Cloud Computing. Is this a good domain for my final year project?

Nowadays computer graphics is widely used for digital art, education, graphic design, video games,virtual reality etc. If u r seeking for the more information regarding ths topic find out here.

About the Author: Sadiqa says: Mena says: Nishali says: Anonymous says: Swati garg says: Hmingmawia says:The process of adjusting intensities of the pixels along the line to minimize the effect of aliasing is called ant aliasing.

What Is Run Length Encoding? Charlie Choco. Raster or Bitmap images are resolution dependent because of this its not possible to increase or decrease their size without sacrificing on image quality. Some system has multiple bits per pixel, the frame buffer is often referred to as pix map.

Geometric manipulation of modeling primitives, such as that performed by a Geometry Pipeline, is the first stage in computer graphics systems which perform image generation based on geometric models. VECTOR - Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon, which are all based on mathematical expressions, to represent image in computer graphics.

They make multiple passes over the paper to plot color picture. You can tell initgraph to use a particular graphics driver and mode, or to autodetect the attached video adapter at run time and pick the corresponding driver. Pixels are normally arranged in a 2-dimensional grid, and are often represented using dots, squares, or rectangles.
