The Open Scene Graph is a cross-platform C++ OpenGL library for the real-time, photo-realistic rendering of large 3D models. Uses range from visual simulation, to scientific modelling, to games, to whatever you can think of!

Copperspice is a C++ library derived from the existing Qt 4.8 framework. The goal was to change the core design of the libraries, leveraging template functionality and C++11 capabilities. The redesign allowed the Qt Meta-Object Compiler (moc) system to be completely removed. Moc is a code generator and does not support many aspects of C++ including templates, complex data types, static type checking, and relies heavily on string comparisons. Removing moc improves runtime performance, reduces the complexity of the build process, and allows more issues to be detected at compile time. Key features: * Qt Meta-Object Compiler (moc) is obsolete * Written in C++11 * Library links directory to any standard C++ application * A template class can inherit from QObject * Copperspice includes several Qt5 classes

LibRaw is a library for reading RAW files obtained from digital photo cameras (CRW/CR2, NEF, RAF, DNG, and others). LibRaw is based on the source codes of the dcraw utility, where part of drawbacks have already been eliminated and part will be fixed in future. The users of the library are provided with API to be built into their software programs. LibRaw is intended to be used in any software that involves RAW file processing for a variety of purposes: RAW converters, data analyzers, panorama stitchers, noise suppressors, etc.

The Progressive Graphics File (PGF) is an efficient image file format that is based on a fast, discrete wavelet transform with progressive coding features. PGF can be used for lossless and lossy compression.

Anti-Grain Geometry (AGG) is an Open Source, free of charge graphic library, written in industrially standard C++. AGG doesn't depend on any graphic API or technology. Basically, you can think of AGG as of a rendering engine that produces pixel images in memory from some vectorial data. But of course, AGG can do much more than that. The ideas and the philosophy of AGG are: * Anti-Aliasing. * Subpixel Accuracy. * The highest possible quality. * High performance. * Platform independence and compatibility. * Flexibility and extensibility. * Lightweight design. * Reliability and stability (including numerical stability).

Quantum GIS (QGIS) is a user friendly Open Source Geographic Information System. QGIS supports vector, raster, and database formats. QGIS is licensed under the GNU GPL. Some of the major features include: - Support for spatially enabled PostGIS tables - Support for shapefiles, ArcInfo coverages, Mapinfo and other formats - Raster support for a large number of formats - Identify features - Display attribute tables - Select features - GRASS Digitizing - Feature labeling

Tiled is a general purpose tile map editor. It's built to be easy to use, yet flexible enough to work with varying game engines, whether your game is an RPG, platformer or Breakout clone. Tiled is free software and written in C++, using the Qt application framework. The main features in a nutshell: * General purpose tile map editor with XML-based map format * Supports orthogonal and isometric maps * Custom objects can be placed with pixel precision * Full undo/redo and copy/paste support * Add custom properties to tiles, layers, objects or the map * Automatically reloads tilesets when changed externally * Resize or offset your tile map later as needed * Efficient tile editing tools like stamp and fill brushes * Supports input/output plugins to open and save files in custom formats

LuxRender is a physically based and unbiased rendering engine. Based on state of the art algorithms, LuxRender simulates the flow of light according to physical equations, thus producing realistic images of photographic quality. Some of the main features of LuxRender are: * biased and unbiased rendering: Users can choose between physical accuracy (unbiased) and speed (biased); * full spectral rendering: Instead of the RGB colour spectrum, full spectra are used for internal calculations; * hierarchical procedural and image based texture system: Procedural and image based textures can be mixed in various ways, making it possible to create complex materials; * displacement mapping and subdivision: Based on procedural or image textures, object surfaces can be transformed; * network and co-operative rendering: Rendering time can be reduced by combining the processing power of multiple computers; * perspective (including shift lens), orthographic, and environment cameras; * HDR output: Render output can be saved in various file formats, including .png, .tga, and .exr. Fully functional exporters are available for Blender and Maya, while exporters for a growing number of 3D applications are under development.

Mandelbulber is an experimental application that helps to make rendering 3D Mandelbrot fractals much more accessible. A few of the supported 3D fractals: Mandelbulb, Mandelbox, BulbBox, JuliaBulb, Menger Sponge, Quaternion, Trigonometric, Hypercomplex, and Iterated Function Systems (IFS). All of these can be combined into infinite variations with the ability to hybridize different formulas together.

MakeHuman(C) is an open-source, open graphics library, stand-alone, multi-platform, software program, which is completely written in C language. Its purpose is to provide a versatile, professional and extremely specialized application for parametrical modeling of three-dimensional humanoid characters.
