Q1. Illustrate how a TFT display device works? Describe the source of light in a TFT display?
Q2. prepare down the Bresenhem’s circle drawing algorithm. Why co-ordinates of just one eighth of the total pixels lying on the circumference of a circle are find outd? How coordinates of other pixels are find outd?
Q3. prepare down the digital differential analyzer algorithm for the line drawing.
Q4. prepare down the scan line fill algorithm and use the algorithm to fill the polygon bounded by the lines joining vertices: (1, 1), (2, 3), (4, 2) and (5, 1).
Q5. Employ Cohen-Sutherland algorithm to clip the line (1, 2) P1 to (8, 5) P2 with respect to the clipping window given by 0 ≤ x ≤ 7, 0 ≤ y ≤ 4.
Q6. Derive a matrix to shear an object by unit 5 all along X-axis and then by unit 4 all along the Y-axis.
Q7. What do you mean by affine transformation? What characteristics of an object are retained after transforming it from one reference frame to the other?
Q8. How a vanishing point is associated to the perspective projection? Can we think of a perspective projection devoid of a vanishing point?
