Goptical is the GNU Optical design and simulation library. It provides model classes for optical components, surfaces, and materials and enables building of optical systems by creating and placing various optical components in a 3D space and simulating light propagation through the system. Classical optical design analysis tools can be used on optical systems. It takes advantages of the C++ object model to allow the building of complex optical systems with a few class instantiations, as optical components are represented by language objects.

ICSILog is a C-language implementation of a fast single-precision approximation of the natural logarithm with adjustable accuracy. The core idea is to use a quantized version of the mantissa of the input floating point number as a pointer into a lookup table. The amount of quantization of the mantissa determines the table size and therefore the accuracy. Current processors are able to store relatively large lookup tables in cache memory. Therefore an acceptable accuracy can be reached without too many main memory accesses.

The LA library provides a C++ vector and matrix class with an interface to BLAS and LAPACK linear algebra libraries and a few additional features. Templates (including some simple template metaprogramming) are employed in order to achieve generic applicability of the algorithms. In particular, iterative methods suitable for sparse matrices can be applied to your custom matrix class, which does not need to provide any explicit storage of the matrix elements (only matrix times vector operation has to be implemented).

FreeSG is a portable, high-level 3D engine with an emphasis on generality. It is designed as a component to be integrated, as opposed to an application framework. Its goal is to support applications ranging from small 3D games running on portable consoles to large simulations that must be rendered photorealistically using fourth-generation graphics hardware.

SPFPM (Simple Python Fixed-Point Module) is a Python module which provides basic facilities for manipulating (binary) fixed-point numbers. The number of fractional binary digits is tunable, allowing near-arbitrary precision arithmetic. Arithmetic and mathematical functions such as sqrt, exp, log, sin, and cos are available.

JGraphpad Pro is a complete application framework for rapid development of JGraph tools. It is meant for developers who wish to provide a stand-alone, rich-client graph application. The user interface is configurable with XML and it uses a plugin architecture for extra functionality. It features a wide range of application components like palette, overview, the ability to export to many image and XML formats, copy and paste, drag and drop, rich text labels, database or backend connectivity, and visual complexity management. You can use it to create workflow editors, call graphs, CAD tools, network diagrams, database visualization tools, and more.
