The Open Asset Import Library loads more than 40 3D file formats into one unified data structure. Additionally, assimp features various mesh post processing tools: normals and tangent space generation, triangulation, vertex cache locality optimization, removal of degenerate primitives and duplicate vertices, sorting by primitive type, merging of redundant materials and many more.

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

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.

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.

MMM is a shared memory protocol for virtualising access to framebuffer graphics, audio output and input event.

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

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.

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).

SuperFamiconv is a converter for tiled graphics, supporting the graphics formats of the SNES, Game Boy Color and PC Engine game consoles. Automated palette selection is supported.

When a GPU renders triangle meshes, various stages of the GPU pipeline have to process vertex and index data. The efficiency of these stages depends on the data you feed them; this library provides algorithms to help optimize meshes for these stages, as well as algorithms to reduce the mesh complexity and storage overhead.

Goxel is a voxel editor that features unlimited scene size, unlimited history buffer, 24-bit RGB colors, layers, procedural rendering, ray tracing, and export to various formats including the format used by Magicavoxel.

Monado is an OpenXR runtime delivering immersive experiences such as VR and AR on mobile, PC/desktop, and any other device. Monado aims to be a complete and conforming implementation of the OpenXR API made by Khronos.

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.

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

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.

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

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.

POV-Ray is short for the Persistence of Vision Raytracer, a tool for producing high-quality computer graphics. POV-Ray creates three-dimensional, photo-realistic images using a rendering technique called ray-tracing. It reads in a text file containing information describing the objects and lighting in a scene and generates an image of that scene from the view point of a camera also described in the text file. Ray-tracing is not a fast process by any means, but it produces very high quality images with realistic reflections, shading, perspective and other effects.

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

DirectFB is a graphics library which was designed with embedded systems in mind. It offers maximum hardware accelerated performance at a minimum of resource usage and overhead.

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

Boolean operations on paths which uses a super fast polygon clipper library by Angus Johnson.

PyGraphviz is a Python interface to the Graphviz graph layout and visualization package. With PyGraphviz you can create, edit, read, write, and draw graphs using Python to access the Graphviz graph data structure and layout algorithms.

The purpose of dot2tex is to give graphs generated by Graphviz a more LaTeX friendly look and feel. This is accomplished by converting xdot output from Graphviz to a series of PSTricks or PGF/TikZ commands. This approach allows:

• Typesetting labels with LaTeX, allowing mathematical notation

• Using native PSTricks and PGF/TikZ commands for drawing arrows

• Using backend specific styles to customize the output
