Latest Computer Graphics Interview Questions
What Is Scan Conversion?
A major task of the display processor is digitizing a picture definition given in an application program into a set of pixel-intensity values for storage in the frame buffer. This digitization process is called scan conversion.
Write The Properties Of Video Display Devices?
Properties of video display devices are persistence ,resolution, and aspect ratio.
What Is Rasterization?
The process of determining the appropriate pixels for representing picture or graphics object is known as rasterization.
Define Computer Graphics.
Computer graphics remains one of the most existing and rapidly growing computer fields. Computer graphics maybe defined as a pictorial representation or graphical representation of objects in a computer.
Name Any Four Input Devices?
Four input devices are keyboard, mouse, image scanners, and trackball.
Write The Two Techniques For Producing Color Displays With A Crt?
Beam penetration method, shadow mask method.
What Is Vertical Retrace Of The Electron Beam?
In raster scan display, at the end of one frame, the electron beam returns to the left top corner of the screen to start the next frame.
Short Notes On Video Controller?
Video controller is used to control the operation of the display device. A fixed area of the system is reserved for the frame buffer, and the video controller is given direct access to the frame buffer memory.
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 Electroluminescent Display?
In plasma panel display, the region between two glass plates is filled with neon gas. In thin film electroluminescent 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.
