11. Diagram shows how the LEDs are placed on the wall. The image is referenced using Cartesian coordinates with the origin at the centre of the image. The LEDs are positioned in practice using a string of length 100" fixed at the image origin and rotated in 45 degree steps. Label the LEDs A, B, C, D, E, F, G, H and determine the coordinates in polar form. LED Location 150 100 50 50 -50 -100 -150 100 150 1 -50 1100 150 inches 12. For a 200" diagonal image and with the display set to 1024 x 768 pixels, where should the points be located on the LCD screen (in screen coordinates)? 13. In a particular set-up, the screen PC generated points are located at positions: A' = (110,-40) B' = (110, 30) C' = (40, 30) D'= (-30, 30) E' = (-30,-40) F' = (-30, -110) G' = (40, -110) H' =(110, -110) Plot these points on graph paper. What scaling and offset adjustment is required so that the points coincide with the LED positions? Calculate the direction and angle the projector has to be moved to get the required translation and scaling
