Explanation: 3D display devices allows user to view the object from different sides. Which display devices allows us to walk around an object and view it from different sides. ![]() Which display devices allow us to walk around an object and view it from different sides? ![]() What is the main reason behind developing algorithms for scan conversion?Įxplanation: The algorithms are being developed in the Scan conversion technique because of its faster rate of generation of objects and efficient use of memory. Random system produces smooth line drawings because the CRT beam follows the line path directly. Raster system produces jagged lines that are plotted as discrete point sets. Is raster scan less expensive than random scan? Raster images are made of pixels, or tiny dots that use color and tone to produce the image. Raster images are made up of tiny pixels, making them resolution dependent and best used for creating photos. Vector graphics are digital art that is rendered by a computer using a mathematical formula. Analog television has discrete scan lines (discrete vertical resolution), but does not have discrete pixels (horizontal resolution) – it instead varies the signal continuously over the scan line. In a raster scan, an image is subdivided into a sequence of (usually horizontal) strips known as “scan lines”. What is scan line in raster scan display? Which of the following is a better option for drawing a smooth line on the screen?Įxplanation: The Random scan display algorithm is best suited for line drawing because it uses an electron beam which operates like a pencil to create a line on the screen. It stores picture definition as a set of intensity values of the pixels in the frame buffer. While in which, for image or picture rendering, raster scan uses pixels. It is suitable for applications requiring polygon drawings. In random scan, mathematical function is used for image or picture rendering. What are the differences between raster scan and random scan? A raster graphic, such as a gif or jpeg, is an array of pixels of various colors, which together form an image. The main difference between vector and raster graphics is that raster graphics are composed of pixels, while vector graphics are composed of paths.
