Jatin Sharma. Raster Graphics, which is the representation of images as an array of pixels, as it is typically used for the representation of photographic images. Abhishek Manjunath. In the CRT, heat is applied to the cathode by directing a current through a coil of wire, is called filament. Sarath S Nair. Trying to reproduce colors accurately also requires some knowledge of gamma. Therefor better print quality is achieved.
Image resolution describes the detail an image holds. The term applies equally to digital images, film images, and other types of images. Higher resolution means more image detail. Define Wavelength? Wavelength is the distance between repeating units of a propagating wave of a given frequency. What is an Electromagnetic Spectrum?
The electromagnetic EM spectrum is the range of all possible electromagnetic radiation frequencies. Define Halftone? Halftone is the reprographic technique that simulates continuous tone imagery through the use of dots, varying either in size or in spacing. Define WCS? World Coordinate Systems. While every point in the FITS data array can be located in the coordinate system determined by the array axes.
World Coordinate Systems WCS are any coordinate systems that describe the physical coordinate associated with a data array, such as sky coordinates. What is OpenGL? OpenGL R is the software interface for graphics hardware that allows graphics programmers to produce high-quality color images of 3D objects.
OpenGL is a rendering only, vendor neutral API providing 2D and 3D graphics functions, including modeling, transformations, color, lighting, smooth shading, as well as advanced features like texture mapping, NURBS, fog, alpha blending and motion blur. OpenGL works in both immediate and retained display list graphics modes. OpenGL is window system and operating system independent. Also, OpenGL is network transparent. What are the benefits of OpenGL for hardware and software developers?
How does the camera work in OpenGL? As far as OpenGL is concerned, there is no camera. More specifically, the camera is always located at the eye space coordinate 0. This is commonly referred to as the viewing transformation. In practice this is mathematically equivalent to a camera transformation but more efficient because model transformations and camera transformations are concatenated to a single matrix.
For example to position a light source in world space it most be positioned while the viewing transformation and only the viewing transformation is applied to the MODELVIEW matrix. How do I implement a zoom operation? A simple method for zooming is to use a uniform scale on the ModelView matrix. 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. Some Important Questions Total Views: Computer Graphics. About the Author: Sadiqa says: Mena says: Nishali says: Anonymous says: What is bitmap? Some system has only one bit per pixel; the frame buffer is often referred to as bitmap. Differentiate plasma panel display and thin film electro luminescent display? In plasma panel display, the region between two glass plates is filled with neon gas.
In thin film electro luminescent display, the region between two glasses plates are filled with phosphor, such as zinc sulphide doped with manganese. What is resolution? The maximum number of points that can be displayed without overlap on a CRT is referred to as the resolution. What is horizontal retrace of the electron beam? In raster scan display, the electron beam return to the left of the screen after refreshing each scan line, is called horizontal retrace of the electron beam.
What is filament? In the CRT, heat is applied to the cathode by directing a current through a coil of wire, is called filament.
What is pixel map? 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? 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.
