Q1. Prepare the Bresenham circle generation algorithm to draw an arc of the circle, whose centre is lying at origin and radius R. The arc must begin from the y axis, and continue till it meets the line making an angle of 135o with x-axis (line passing through the origin and point (–1, 1)).

Q2. describe the scan line seed fill algorithm to produce solid area on the screen.

Q3. Use the Cyrus Beck algorithm to find out the portion of line between P1(50,50) and P2(80,35) which gets clipped by the window K(20,0), L(60,0), M(60,40), N( 20,40), T(0,20). Prepare the complete Cyrus Beck table and show all computations.

Q4. Describe the Gouraud surface rendering technique for displaying an object.

Q5. How solid can be produced by using sweep methods? Describe it by constructing a cylinder parallel to z axis with base centered at (30,60,0), radius 10, and length 70.

As well describe the steps to construct a solid cone lying on the xz plane with base radius 30 and cone tip situated at (70,30,70).

Q6. describe the 4 tests used to find out if two surfaces S and R need not be ordered if carrying out the depth sorting method (that is, Painters algorithm).
