Flat Panel Displays - Hardware Primitives
1. Flat panel displays have now become more common. These include liquid crystal displays (LCD) and thin film electroluminescent displays.
2. In raster or random scan display systems a special purpose processor for graphics is used and is called graphics controller.
Explain the advantage and disadvantage of Raster CRT Advantages Allows solids, not just wireframes Leverages low-cost CRT technology (i.e., TVs) Bright, i.e.
Write short notes on active and passive transformations? In the active transformation the points x and x represent different coordinates of the similar coordinate system. Here
Need for Video Compression: T he high bit rates that result from the various types of digital video make their transmission through their intended channels very difficult. Eve
what is image precision?
Steps uses in the Cohen Sutherland Line Clipping Algorithm are: Figure: Steps for Cohen Sutherland Line Clipping STEP 1: Input: x L , x R , y T , y B
Algorithm (scan-line): For each scan line perform from step (1) to (3). 1) For all pixels on a scan-line, arrange depth [x]=1.0 i.e. max value and Intensity [x] = background
Define the working procedure of CRT with diagram
Background Texturing is like wallpapering; you are pasting an image onto the OpenGL Quad primitive. Recall that GL_QUAD is specified by four vertices. An image, or a texture,
Functioning of Input Devices Functioning of input devices-Keyboard, mouse, trackball and space ball, Joystick, data glove, digitizer, scanner, touch panel, light pen, voice sys
1. By using Digital Differential Analyzer algorithm draw line segments from point (1,1) to (9,7). Ans. We see that the usual equation of the line is specified by: y = mx+c
