a) With a neat diagram explain the components of a graphic system
b) A monitor has a pixel addressability of 800X600 and color depth of 24 bits. Calculate the minimum amount of display memory required on its adapter card to display an image on the screen.(2+3)
2)
a) Derive an equation to map a point (xw, yw) from a window defined by the co-ordinate (xwmin, ywmin, xwmax, ywmax) to a point (xv,yv) in viewport . Viewport is defined by the co-ordinates (xvmin,yvmin,xvmax,yvmax).
