Introduction : As a part of our me451 course titled
Computer Aided Engineering and Design we have done this project. In
computer aided manufacturing where automated machining might have to be done,
visibility of different parts of the proposed product is to be determined and
there we can find the application of these techniques. Or during the design
process of a certain product where its aesthetics have to be paid attention to,
these techiniques may be used for the graphical rendering of the product. For
example in an automobile industry the apperance of the product is a critical
factor.
