• PIC (for troff/groff)

• MetaPost (for usage with TeX/LaTeX)

• LaTeX2e picture

• GNU Metafile (for use with plotutils/libplot)

• Any format supported by ImageMagick

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!

GNU Paint is a simple, easy-to-use paint program for the GNOME environment. It supports drawing freehand as well as basic shapes and text. It features cut-and-paste for irregular regions or polygons.

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.

OpenSubdiv is a set of libraries that implement high performance subdivision surface (subdiv) evaluation on massively parallel CPU and GPU architectures.

This package provides a common standard tangent space library used in baking tools to produce normal maps.

Skia is a 2D graphics library for drawing text, geometries, and images. It supports:

• 3x3 matrices with perspective

• antialiasing, transparency, filters

• shaders, xfermodes, maskfilters, patheffects

• subpixel text

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).

Mmg is a collection of applications and libraries for bidimensional and tridimensional surface and volume remeshing. It consists of:

• the mmg2d application and library: mesh generation from a set of edges, adaptation and optimization of a bidimensional triangulation and isovalue discretization;

• the mmgs application and library: adaptation and optimization of a surface triangulation and isovalue discretization;

• the mmg3d application and library: adaptation and optimization of a tetrahedral mesh, isovalue discretization and Lagrangian movement;

• the mmg library gathering the mmg2d, mmgs and mmg3d libraries.

This package contains OpenXR headers, as well as source code and build scripts for the OpenXR loader.

Anti-Grain Geometry is a high quality rendering engine written in C++. It supports sub-pixel resolutions and anti-aliasing. It is also a library for rendering SVG.

MiniFB (Mini FrameBuffer) is a small, cross-platform library that makes it easy to render (32-bit) pixels in a window.

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.

Open Shading Language (OSL) is a language for programmable shading in advanced renderers and other applications, ideal for describing materials, lights, displacement, and pattern generation.

OpenEXR provides the specification and reference implementation of the EXR file format. The purpose of EXR format is to accurately and efficiently represent high-dynamic-range scene-linear image data and associated metadata, with strong support for multi-part, multi-channel use cases.

F3D (pronounced /fɛd/) is a VTK-based 3D viewer with simple interaction mechanisms and which is fully controllable using arguments on the command line. It supports a range of file formats (including animated glTF, STL, STEP, PLY, OBJ, FBX), and provides numerous rendering and texturing options.

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