Acknowledgement

I would like to acknowledge Professor Stephen Mann for all his generous help throughout the term. Professor Mann offered many insights and advice in designing of this project as well as algorithm implementation. Special thanks to my friend Calvin Ho, for providing me with his wonderful OBJ models. Calvin also helped me implement the mesh import/load functions. I would also like to thank Elodie Fourquet, for encouraging me to take this course, and providing valuable opinions on the design of this project.
