Q1. describe the illumination model comprising of ambient, diffusively reflected and specularly reflected components.

Q2. Find out the cubic Bezier curve defined by the control points P0(10, 50), P1(10, 40), P2(40, 20) and P3(0, 0) as a plane curve in Z = 0 plane? By using the above curve as the base curve, get the surface of revolution by rotating the curve around the Y-axis. Draw a rough diagram of the base curve and surface. (Illustrate the projection of surface on z = 0 plane)

Q3. Illustrate the merits and demerits of the Octree based representation of solids.

Q4. Determine the rotation transformation matrix to make the line segment joining from (0, 0, 0) to (4, 0, 5) to coincide with positive side of the Z-axis?

Q5. In brief describe the circle generation method by using Bresenham’s algorithm. Point out how one quarter of a circle can be produced with centre at origin and Radius R.
