The scale factor of viewport transformation for x co-ordinate is ________ a) Sy = (svmax + svmin)/ (swmax + swmin) b) Sy = (svmax – svmin)/ (swmax + swmin) c) Sy = (svmax – svmin)/ (swmax – swmin) d) Sy = (svmax + svmin)/ (swmax – swmin)
The correct answer is (a) Sx = (svmax – svmin)/ (swmax – swmin) For explanation: The mapping or transformation involves developing formulas that start with a point in the world window, say (xw, yw). The formula is used to produce a corresponding point in viewport coordinates, say (xv, yv). So after keeping it proportional in ‘x’ co-ordinate, we get, (svmax– svmin)/ (swmax – swmin).Read more on Sarthaks.com - https://www.sarthaks.com/2466378/the-scale-factor-of-viewport-transformation-for-x-co-ordinate-is
