We would like to take this opportunity to express our sincere thanks to Prof.Bruce Land for his guidance, encouragement and support during the course of our project work at Cornell university. He always listened to us and was there to help when we ran into problems.
We would also like to thank Prof. Martti Mantyla and Prof. Timo Laakko for all their invaluable help with the numerous questions we had regarding Solid Modeling and their algorithm.
Last but not the least, we would like to thank all our friends at Cornell for putting up with us whenever our project wasn't going as planned. Thanks for being there and helping us keep our sanity.
