Felix is a programming language with a fully featured purely functional subsystem embedded in a a traditional Algol-like imperative programming system. The system features garbage collection, static typing, parametric polymorphism, overloading, regular expression matching, and a lot more. A scripting harness is used to invoke source files, but fully compiled binary shared libraries are generated, yielding both rapid prototyping and high performance. Seamless binding of C/C++ code makes interfacing existing libraries easy. Control inversion provides language-level cooperative multi-tasking.
openEMS is an electromagnetic field solver using the FDTD method. It employs a fully 3D Cartesian and cylindrical coordinate graded mesh. Matlab (or Octave) is used as an easy and flexible scripting interface. Advanced Features include: multi-threading, SIMD (SSE), and MPI support for high speed FDTD.
crunch/crnlib is a lossy texture compression tool and library for developers that distributes and uses content in the DXT1/5/N or 3DC/BC5 compressed mipmapped texture formats. crnlib can compress mipmapped 2D textures and cubemaps to .8-1.25 bits/texel, and normal maps to 1.75-2 bits/texel. crnlib's quality and performance is competitive to transform-based solutions, or other offline/real-time DXTn compressors such as squish or ATI_Compress. crnlib implements a new form of "clustered" DXTn compression, with a compressed texture data format that was carefully designed to be very quickly transcodable directly to raw DXTn texture bits with no intermediate recompression step or individual pixel-level operations. The typical single threaded transcode to DXTn rate is equivalent to 100-250 megatexels/sec. Fast random access to individual mipmap levels is supported.
DeltaQt is a cross-platform library of C++ classes and functions for parsing of DELTA (DEscription Language for TAxonomy) files, and is part of the Free DELTA initiative. Support for all major data-related DELTA directives is planned. Typesetting directives are beyond the scope of the project, and support for them is not planned. Support for RTF formatting within comments, notes, descriptions, etc. is planned. All data defined by supported DELTA directives (including comments and annotations) will be parsed into memory. Qt (core) is used extensively.
Urban Lightscape is a photo filter for exposure correction, localized brightness adjustments, dodging and burning, and the introduction of synthetic lighting to a photo. A simple "double-click-and-drag" paradigm is used to place control points on a photo, and clever edge detection localises and interpolates lightness adjustments around and between these points. Results are rapid, with additional controls for more subtle refinements.
