This is an extension of the graphics library VTK. The goal of the extension is to equip the library with boolean operations on polygonal meshes. I started the project at the end of my studies in mechanical engineering at the University of Applied Sciences (HTWK) in Leipzig. I used VTK to develop a program, which I had to create for a paper. At this time I would have wished, that this feature already exists. There was several implementations from third parties, but after some tests, I came to the conclusion, that none of them worked correct. The once who worked was bound to other big libraries like CGAL. I decided to start with my own implementation. This library is the result of my efforts. Nothing for now.
