Question 1: (2 Marks). Given the circle radius r=6, Demonstrate the midpoint circle algorithm by determining the circle points along all the octant (Complete circle). Question 2: (3 Mark). Consider a triangle with scaling factors Sx = 2, Sy = 1 and angle 90 8 7 6 5 00 4 3 2 C 1 A a) Scale it about the origin using the Matrix b) Scale it about the Reference point (3,4) using the matrix. c) Rotate it about the origin using the Matrix d) Rotate it about the Pivot point (3,4) using the matrix. e) Do two repeated Translation with the Translation factors, (2,1) and (4,3). f) Perform Shear the triangle about x axis by shx=2, After Change the position of the triangle by a vector (2,3). by finding its Composite Matrix.
