I need a library to handle computational geometry in a project, especially boolean operations, but just about every feature is useful. The best library I can find for this is CGAL, but this is the sort of project I would hesitate to make without garbage collection.
What language/library pairs can you recommend? So far my best bet is importing CGAL into D. There is also a project for making Python bindings for CGAL, but it's very incomplete.
I would still recommend to proceed with Python and the existing Python binding. When you find it's incomplete, you'll also find that it is fairly easy to extend - Python's C API is designed so that integrating with external libraries is fairly easy (for experienced C programmers).
Perhaps you can look at Shapely for python

For Java I would use JTS
For .NET I would use SharpMap or .NETTopologySuite
The CGAL-bindings project provides bindings for CGAL using SWIG. The targeted languages, so far, are Java and Python. The CGAL-bindings project is open source, and supported/founded by two french companies.
JTS is also available in .NET via IKVM.
I've just found this and it seems very promising even if it seems a young project: https://pyrr.readthedocs.org/en/latest/index.html#
Pyrr is a Python mathematical library.
and it is based on numpy!
