Hi, my name is Tinko Bartels, I'm studying to get a Master's degree in Mathematics at TU Berlin. I'm interested to work on Boost Geometry. I'm working at the university for a couple of years on C++ projects that rely on Boost libraries, most notably Boost.Geometry. Our work involves the computation of exact covers of spaces with boxes. This motivated my idea to add support to void union_(Geometry1 const & geometry1, Geometry2 const & geometry2, Collection & output_collection) void sym_difference(Geometry1 const & geometry1, Geometry2 const & geometry2, Collection & output_collection) void difference(Geometry1 const & geometry1, Geometry2 const & geometry2, Collection & output_collection) for Geometry1=Geometry2=box and Collection is a collection of boxes. Since I have no merged contributions to open source projects to refer to, I could, for example, provide an implementation of the difference method for types adhering to the box concept and a collection of boxes as output_collection. Since the results of those operations in terms of exact covers of the resulting space with boxes are not uniquely defined and the implementation should take less than 3 months, additional strategies for these specializations of the above algorithms could be added as future milestones. If this endeavor is considered worthwhile by potential mentors, I would get started on writing a proposal right away.
