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.
QUESTION (a) In Automatic Contrast Adjustment briefly explain how to stretch an image to its full intensity (b) Write down a mathematical function of a Modified Automatic Con
Q. What do you mean by image precision and object precision? Describe z- buffer algorithm for visible surface detection. OR What do you mean by image precision and obj
Assumptions for Area Subdivision Method a) ¾ Plane of projection is z=0 plane b) ¾ Orthographic parallel projections c) ¾ Direction of projection as d= (0,0,-1) d
Summary of Graphic Primitives In this all section, we have illustrated the basic graphic primitives that are line, point and circle; we have also illustrated both practical an
To transform from the world coordinate system to viewing coordinate system you need to perform the following operations. a) Translate the viewing coordinate origin to the worl
Disadvantages : 1) Doubles memory needs, one for at least z-buffer and one for refreshes- buffer. 2) Dependency of device and memory intensive. 3) Wasted calculation u
