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).

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.

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

Motion graphics has a wide variety of uses, including:

• Television and film: Title sequences, commercials, and visual effects

• Web design: Animated logos, banners, and interactive elements

• Social media: Animated posts and stories

• Presentations: Animated infographics and slideshows

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.

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

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

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.

Basis Universal is an LDR/HDR GPU compressed texture interchange system supporting transcoding to a large number of GPU texture formats.

Drawpile is a drawing program that allows share the canvas with other users in real time.

Some feature highlights:

• Shared canvas using the built-in server or a dedicated server

• Record, play back and export drawing sessions

• Simple animation support

• Layers and blending modes

• Text layers

• Supports pressure sensitive Wacom tablets

• Built-in chat

• Supports OpenRaster file format

• Encrypted connections using SSL

• Automatic port forwarding with UPnP

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

facedetect is a face detector for batch processing. It answers the question: "Is there a face in this image?" and gives back either an exit code or the coordinates of each detect face in the standard output. facedetect is used in software such as fgallery to improve the thumbnail cutting region, so that faces are always centered.

OpenCSG is a library for rendering Constructive Solid Geometry (CSG) using OpenGL. CSG is an approach for modeling complex 3D-shapes using simpler ones. For example, two shapes can be combined by uniting them, by intersecting them, or by subtracting one shape from the other.

ASLI (A Simple Lattice Infiller) is a command-line tool that allows users to fill any 3D geometry with a functionally graded lattice. The lattice infill is constructed out of unit cells, described by implicit functions, whose type, size and feature can be varied locally to obtain the desired local properties.

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 is a headers-only library that allows approximate convex decomposition of a 3D surface.

OpenVDB is a C++ library comprising a hierarchical data structure and a large suite of tools for the efficient storage and manipulation of sparse volumetric data discretized on three-dimensional grids. It was developed by DreamWorks Animation for use in volumetric applications typically encountered in feature film production.

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.

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

IlmBase provides several utility libraries for C++. Half is a class that encapsulates ILM's 16-bit floating-point format. IlmThread is a thread abstraction. Imath implements 2D and 3D vectors, 3x3 and 4x4 matrices, quaternions and other useful 2D and 3D math functions. Iex is an exception-handling library.

This package provides a header only C++11 glTF (GL Transmission Format) 2.0 library.

GL Transmission Format (glTF) is a royalty-free specification for the efficient transmission and loading of 3D scenes and models by applications. glTF minimizes both the size of 3D assets, and the runtime processing needed to unpack and use those assets. glTF defines an extensible, common publishing format for 3D content tools and services that streamlines authoring workflows and enables interoperable use of content across the industry.

NanoSVG is a simple single-header SVG parser. The output of the parser is a list of cubic bezier shapes. The library suits well for anything from rendering scalable icons in an editor application to prototyping a game.

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

• 3x3 matrices with perspective

• antialiasing, transparency, filters
