There are many buggy floating point boolean op libraries out there. Why do we need another?
I would like to ask you to refrain from spreading FUD with regards to the library under review without any concrete proof.
I don't think this is a fair appraisal of my statements. It is common knowledge in computational geometry that floating point operations in boolean operations (orientation tests, intersections...) are inherently flawed and so in the absence of any proof by the authors that they have attempted to compensate I think it is justified to bring up these points. There has been some insinuation in recent posts that the GGL Boolean Ops could be used to perform floating point boolean operations as a proxy for Boost.Polygon. Such a usage would require that we know if the implementation actually works. It wasn't intended as a personal attack on GGL. Brandon
