Department of Mechanical Engineering
Fifth Semester
ME6501 Computer Aided Design
November / December 2015 Exam Important Questions
(Regulation 2013)
1. A scaling factor of 2 is applied in the Y direction while no scaling is applied in the X direction to
the line whose two end points are at coordinates (1, 3) and (3,6).The line is to be rotated subsequently through 300, in the counter clockwise direction. Determine the necessary transformation matrix for the operation and the new coordinates of the end points.
2. What is meant by Interactive Computer Graphics? Explain its various elements.
3. Briefly explain the Clipping and Line drawing with an example
4. What are the reasons for implementing a computer aided design system
5. Discuss the modeling guidelines to be followed by the user while constructing a surface model CAD/CAM system.
6. Differentiate between Bezier and 8- spline surface with reference to number of control points, order of continuity andsuriace normal.
7. What do you mean by blending function? Explain rep of a surface.
8. Briefly explain C56 and B-Rep of solid modeling techniques
9. Explain the surface algorithms for surface hidden removal of an abject.
10. Write note on sample hidden line algorithms.
11. Write notes on Frame-Buffer animation and animation techniques with an example.
12. Explain key frame technique of computer animation with an example
