Polygon and line clipping and offsetting library (C++, C#, Delphi)
The Clipper library performs clipping and offsetting for both lines and polygons. All four boolean clipping operations are supported - intersection, union, difference and exclusive-or. Polygons can be of any shape including self-intersecting polygons. 17 March 2016: Since it's been some time since the last update, some may be wondering if I no longer plan further updates. I do have plans for more updates but I also have a chronic health condition (not life threatening) that's set me back...
STXXL is an implementation of the C++ standard template library STL for external memory (out-of-core) computations, containers, and algorithms that can process huge volumes of data that only fit on disks.
C++ library for working with OWL ontologies
Library of generic, k-d tree multi-dimensional containers
Spatial is a generic header-only C++ library providing multi-dimensional in-memory containers, iterators and functionals. Spatial is a general purpose library with good overall performance thanks to its self-balancing k-d tree containers. Spatial makes it easy to search for nearest neighbors, orthogonal ranges, or perform ordering of objects in any number of dimensions. Spatial's design borrows heavily from the STL, and strives to follow it's elegant interface; therefore Spatial's containers...

Extreem Reader for Cosmological simulation data P-Gadet2 and ART codes.It conserves memory by using memory mapped files. Contains some basic analysis tools such a KD-Tree, Minimum Spanning Tree, and rendering module using PMViewer algorithm.
C++ wrapper for the OpenGL (Version 3 and higher) API
OGLplus is a open-source header-only library which implements a thin object-oriented facade over the OpenGL® (version 3 and higher) C-language API. It provides wrappers which automate resource and object management and make the use of OpenGL in C++ safer and easier.
Halite is an open-source BitTorrent client and is based on the excellent libtorrent library from Rasterbar Software. The remote control interface for Halite has been put on the back burner while the more pressing features that a bittorrent client needs.
The database access library for C++ programmers that provides the illusion of embedding SQL in regular C++ code, staying entirely within the C++ standard.
The CML (Configurable Math Library) is a free, open-source C++ vector, matrix, and quaternion math library designed for use in games, graphics, computational geometry, and related applications. Please note: the CML source has moved to GitHub: https://github.com/demianmnave/CML
Pugg is a c++ framework for plugin management. Features o Header only library, no installation o Auto loading of plugins from files o Version control for plugins o Object oriented design o Platform independent
CVM C++ Class Library encapsulates concepts of vector and square, band, symmetric and hermitian matrices in Euclidean space of real and complex numbers. It utilizes BLAS and LAPACK Fortran libraries. See http://cvmlib.com for binaries and more details.
C++ code to count the number pages in a given PDF file.
This C++ library contains the 'PdfPageCount' class that performs the single task of finding the number of pages in a given PDF document. While the PdfPageCount class is very simple to use, the contained code is complex because the page count can be hidden in any number of places, quite often within compressed data.
A Fast Duplicate File Detector with graph based semi-automatic cleaner
DupLichaSe is a very fast Duplicate File Detector that uses inductive heuristics to detect duplicate files very fast; based on content! DupLichaSe stands out from EVERY other Duplicate file detection Software because of it's graph based semi-automatic selection system. ... after finding 100s of duplicate files, do you have to go through some manual and possibly laborious process of deleting the duplicates? ...or is there a way for the Software to learn and do most of it for you in a SAFE...
client and server HTTP(S) library for Boost C++ developers
The motivation of pion is not to build yet another web server or web application framework, but to help provide basic HTTP(S) functionality to new or existing C++ applications. If you're working on a Boost C++ application and would just like to use HTTP to provide a simple user interface or interact with run-time data, then pion might be for you.
character set conversion library
charset is a c++ template library that aim to provide simple interface to convert between different character sets, the default implementation uses Unicode as the middle layer (also you can use Unicode, as source or target of conversion).
Fixed-length Arithmetic-types library
MathX is a fixed-length arithmetic-types written in pure c++ templates. The goal is to provide signed-integer, unsigned-integer, IEEE-754 float-point and fixed-point types, all with specific number of bits. To this moment, only signed-integer and unsigned-integer are completed for little-endain architecture. Any compiler that support c++03 or c++11 can successfully compile MathX. Refer to README for more information.
A Boost.Application allows a developer run your application as a Windows service, as a Unix/Linux daemon, or as a usual interactive application (terminal) without the need to add extra code, the library abstract OS specific API and provide a ease common interface. To version beta4 (aspect based), check :https://github.com/retf/Boost.Application
A C++ Library meant to make parallelization a breeze.
This library will be design with only the features provided by the new C++11 standard. This means that the code will compile with any platform and compiler that supports the new standard. The goal of this project is to allow developers to easily add parallelization to their code without having to mess around with the perils of concurrency. This library will focus mostly on parallelizing data processing and will use a dependency system to make sure a series of operations to be performed on data...
This is a C++ logging library implementation which is accepted to Boost. It aims for extensibility and flexibility while moderately affecting user's application performance. Since being accepted, the library is developed and distributed as a part of Boost. Please, visit www.boost.org for more info.
Cross-platform C++ libraries with a network/internet focus.
NOTE: Current source code as well as bugs/patches are on GitHub: https://github.com/pocoproject/poco/ C++ class libraries for network-centric, portable applications, integrated perfectly with the C++ Standard Library. Includes network protocols (Sockets, HTTP, FTP, SMTP, POP3, etc.), SQL database access and XML parsing. Licensed under Boost license.
An independent module architecture for C++.
... only, while still allowing extensive reuse. Component proxies are central to the abstraction of the ABI and allow the C++M model to do automatic marshaling of parameters, automatic lifecycle management (RAII) and to support exception handling across component (and compiler/library) boundaries. These proxies are generated with a special pre-compiler from the “module description language”.
