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* Qt Meta-Object Compiler (moc) is obsolete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.
