1) Describe regularized Boolean Set operations in brief. How they are different from standard Boolean set operations? Given a unit cube with one corner at (0, 0, 0) and the opposite corner at (1,1, 1). Indicate cube as pointers to vertex list and pointers to the edge list.
2) Describe the following forms of parametric curves-Hermite, Bezier, Uniform B-spline, and Non uniform B-spline.
3) What are the major type of representations and compare them in terms of the following- Accuracy, Domain, Uniqueness, validity, Closer, Compactness and Efficiency.
4) Briefly describe Gamma Correction. Why it is needed? Describe different methods to increase intensity levels in black and white monitor.
5) Describe RGB and CMY Color model.
6) What is the system architecture of simple raster display system?
7) What do you mean by polyhedral? What is the essential and adequate condition for object to be a polyhedron? Write down the advantages of Winged-edge representation over other boundary representation methods.
8) What do you mean by perspective foreshortening and vanishing point? Derive a formula for perspective projection on xy plane with centre of projection on positive z-axis at a distance d from the origin.
