The Color Transformation Language, or CTL, is a small programming language that was designed to serve as a building block for digital color management systems. CTL allows users to describe color transforms in a concise and unambiguous way by expressing them as programs. In order to apply a given transform to an image, the color management system instructs a CTL interpreter to load and run the CTL program that describes the transform. The original and the transformed image constitute the CTL program's input and output.

2geom is a C++ library of mathematics for paths, curves, and other geometric calculations. Designed for vector graphics, it tackles Bézier curves, conic sections, paths, intersections, transformations, and basic geometries.

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.

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.

Please note that this version requires a processor with SSE2 support.

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.

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.

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

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

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.

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.

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

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.

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

This package contains tools for building documentation with Sphinx, Graphviz and LaTeX.

Library intended to provide a set of useful functions to deal with 3D surfaces meshed with interconnected triangles.

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.

This package provides a Python script to convert the output from many profilers into a dot graph.

It can:

• prune nodes and edges below a certain threshold;

• use an heuristic to propagate time inside mutually recursive functions;

• use color efficiently to draw attention to hot-spots;

• work on any platform where Python and Graphviz is available.

Graphviz is a graph visualization tool suite. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.

This package provides a simple Python interface for the Graphviz graph visualization tool suite.

Xdot is an interactive viewer for graphs written in graphviz’s dot language. Internally, it uses the xdot output format as an intermediate format, and gtk and cairo for rendering. Xdot can be used either as a standalone application, or as a Python library.

Graphviz is a graph visualization tool suite. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.

Pydot provides an interface to create, handle, modify and process graphs in Graphviz's DOT language, written in pure Python.

Grap is a language for typesetting graphs specified and first implemented by Brian Kernighan and Jon Bentley at Bell Labs. It is an expressive language for describing graphs and incorporating them in typeset documents. It is implemented as a preprocessor to Kernigan's pic language for describing languages, so any system that can use pic can use grap. For sure, TeX and groff can use it.
