XaoS is a fast, portable, real-time, and interactive fractal zoomer. It displays the Mandelbrot set (among other escape time fractals) and allows you zoom smoothly into the fractal. Various coloring modes are provided for both the points inside and outside the selected set. In addition, switching between Julia and Mandelbrot fractal types and on-the-fly plane switching is provided.
SGX Engine Core contains the basic functionality which underpins SGX, a 3D graphics engine from Steven Goodwin. It is based around a series of null drivers and loosely-coupled modules to facilitate an infinitely upgradable engine. It is primarily suited to games and digital TV backdrops.
python-colormath is a Python module which abstracts common color math operations. (For example, converting from CIE L*a*b to XYZ, or from RGB to CMYK.) Other operations, such as calculating ANSI and ISO density from spectral data or taking the delta E of two colors, are also covered.
Perl Math::FastGF2 is a Perl math module for performing arithmetic on Galois Fields. Galois Fields have applications in Cryptography (such as the AES encryption system or various threshold systems for sharing secrets) and Error-correcting Codes (eg, Rabin's Information Dispersal Algorithm or Reed-Solomon Codes). It currently implements all the primitive maths operations needed to work with Galois Field polynomials. A set of demo scripts is included that implements Shamir's Secret Sharing algorithm using the module.
Crypt::IDA is a Perl module that implements Rabin's Information Dispersal Algorithm. This is what's known as a "threshold system": a secret is divided into n shares with the property that any k (the "quorum" or "threshold") of those shares (with k <= n) can be combined at a later time to reconstruct the secret. The algorithm should be cryptographically secure in the sense that if fewer shares than the quorum k are presented, no information about the secret is revealed. The module uses Math::FastGF2 to efficiently implement the algorithm, making it suitable for securely sharing and distributing even large files. The Crypt::IDA::ShareFile module implements a file format for creating, storing, and distributing shares created with Crypt::IDA.
POSNUMCON is a command-line (or console mode) program for converting between positional numeral systems written in C++. It is able to convert between any positional numeral system (e.g. decimal, octal, binary and hexadecimal) with base (radix) between 2-36 (there is the possibility for extension). It offers full support for big length, negative, and floating-point (fractional) numbers, saving calculation results to a text file. It is fully and easily customizable.
Convex processing is a quick and efficient library to implement algorithms based on convex analysis. Some specific fields are addressed, such as general image processing and tomography. The graphical interface allows users to play with some reconstruction algorithms in tomography and denoising. For developers, the API is simple, several examples of use are provided, and all important parts are covered by unit tests. This software is intended to help people play, understand, and improve those algorithms.
