Visualization Library is C++ middleware for high-performance 2D and 3D graphics applications based on the industry standard OpenGL 1.x-4.x, designed to develop portable applications for the Windows, Linux and Mac OS X operating systems. It supports advanced features like OpenGL Shading Language, Volume Rendering, Isosurface extraction, Frame Buffer Objects, Multiple Render Targets, Vertex and Pixel Buffer Objects, KdTree/AABB frustum culling, a multilingual Unicode-based text engine, advanced texturing, DDS cubemaps, mipmaps, compressed textures, and much more. Visualization Library can be especially useful in 3D/2D scientific visualization, virtual reality, augmented reality, visual simulation, data visualization, presentations, multimedia applications, special effects, and 3D/2D games.
Theano is a Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently. Theano features tight integration with numpy, transparent use of a GPU, efficient symbolic differentiation, speed and stability optimizations, dynamic C code generation, and extensive unit-testing and self-verification. Theano has been powering large-scale computationally intensive scientific investigations since 2007. But it is also approachable enough to be used in the classroom (IFT6266 at the University of Montreal).
ChaiScript is an embedded scripting language designed from the ground up to directly target C++ and take advantage of modern C++ development techniques. Being a native C++ application, it has some advantages over existing embedded scripting languages. It uses a header-only approach, which makes it easy to integrate with existing projects. It maintains type safety between your C++ application and user scripts. It supports a variety of C++ techniques including callbacks, overloaded functions, class methods, and STL containers.
Netdisco is a Web-based network management tool. Users can locate the switch port of an end-user system by IP or MAC address. Data is stored using a SQL database. Cisco Discovery Protocol (CDP) optionally provides automatic discovery of the network topology. The network is inventoried by both device model and operating system (like IOS). It uses router ARP tables and L2 switch MAC forwarding tables to locate nodes on physical ports and track them by their IP addresses. For each node, a time stamped history of the ports it has visited and the IP addresses it has used is maintained. It gets all its data, including CDP topology information, with SNMP polls and DNS queries. Security features include a wire-side Wireless Access Point (AP) locator.
radlib is a C language library developed to abstract details of interprocess communications and common Linux/Unix system facilities so that application developers can concentrate on application solutions. It encourages developers to use a proven paradigm of event-driven, asynchronous design. By abstracting interprocess messaging, events, timers, and any I/O device that can be represented as a file descriptor, radlib simplifies the implementation of multi-purpose processes, as well as multi-process applications. In short, radlib is a sincere attempt to provide real-time OS capability on a non-real-time OS.
dnscrypt-proxy acts as a DNS proxy between a regular client, like a DNS cache or an operating system stub resolver, and a DNSCrypt-aware resolver, like OpenDNS. The DNSCrypt protocol focuses on securing communications between a client and its first-level resolver. While not providing end-to-end security, it protects the local network (which is often the weakest link in the chain) against man-in-the-middle attacks. It also provides some confidentiality to DNS queries.
G3D is a C++ library for game developers, researchers, and students. It is a base of robust and high performance code common to most 3D projects. It is not a stand-alone graphics or game engine, but is a set of pieces to jump start your own engine or graphics project. The library has two parts: G3D for pure math, and GLG3D for interacting with hardware acceleration via OpenGL. You can use G3D without GLG3D if you want to use another 3D API (like DirectX) or don't like the OpenGL abstraction.
FLENS is short for Flexible Library for Efficient Numerical Solutions. This C++ can be used as a builing block for the implementation of other (higher-level) numerical libraries or numerical applications. It is a C++ library (requires a C++11 conform compiler). Easy install, as FLENS is headers only. It gives you Matrix/vector types for dense linear algebra; a generic (i.e. templated) implementation of BLAS; and a generic reimplementation of LAPACK. If high performance BLAS libraries like ATLAS, GotoBLAS, etc. are available, you simply can link against them and boost performance.
