Coin is a 3D graphics library with an Application Programming Interface based on the Open Inventor 2.1 API. For those who are not familiar with Open Inventor, it is a scene-graph based retain-mode rendering and model interaction library, written in C++, which has become the de facto standard graphics library for 3D visualization and visual simulation software in the scientific and engineering community.

OpenImageIO is a library for reading and writing images, and a bunch of related classes, utilities, and applications. There is a particular emphasis on formats and functionality used in professional, large-scale animation and visual effects work for film.

Embree is a collection of high-performance ray tracing kernels. Embree is meant to increase performance of photo-realistic rendering applications.

GR is a universal framework for cross-platform visualization applications. It offers developers a compact, portable and consistent graphics library for their programs. Applications range from publication quality 2D graphs to the representation of complex 3D scenes. GR is essentially based on an implementation of a GKS. As a self-contained system it can quickly and easily be integrated into existing applications (i.e. using the ctypes mechanism in Python or ccall in Julia).

OGRE (Object-Oriented Graphics Rendering Engine) is a scene-oriented, flexible 3D engine written in C++ designed to make it easier and more intuitive for developers to produce applications utilising hardware-accelerated 3D graphics.

The OpenSceneGraph is a high-performance 3D graphics toolkit used by application developers in fields such as visual simulation, games, virtual reality, scientific visualization and modeling.

This package provides a very basic collection of point, size and rect classes for C++.

FOX (Free Objects for X) is a C++ based Toolkit for developing Graphical User Interfaces easily and effectively. It offers a wide, and growing, collection of Controls, and provides state of the art facilities such as drag and drop, selection, as well as OpenGL widgets for 3D graphical manipulation. FOX also implements icons, images, and user-convenience features such as status line help, and tooltips. Tooltips may even be used for 3D objects!

Alembic is a computer graphics interchange framework. It distills complex, animated scenes into a set of baked geometric results.

Blender is a 3D graphics creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. The application can be customized via its API for Python scripting.

FGallery is a static, JavaScript photo gallery generator with minimalist look. The result can be uploaded on any web server without additional requirements.

Flux is an interface description language used by DirectFB. Fluxcomp compiles .flux files to .cpp or .c files.

Friction is a versatile motion graphics application that allows you to create vector and raster animations for web and video.
