The plfit command fits power-law distributions to empirical (discrete or continuous) data, according to the method of Clauset, Shalizi and Newman (Clauset A, Shalizi CR and Newman MEJ: Power-law distributions in empirical data. SIAM Review 51, 661-703 (2009)).

rw computes rank-width and rank-decompositions of graphs.

Faiss is a library for efficient similarity search and clustering of dense vectors. This package provides Python bindings to the Faiss library.

Faiss is a library for efficient similarity search and clustering of dense vectors. It contains algorithms that search in sets of vectors of any size, up to ones that possibly do not fit in RAM. It also contains supporting code for evaluation and parameter tuning.

The PyGSP is a Python package to ease signal processing on graphs.

This package provides a library for the analysis of networks and graphs. It can handle large graphs very well and provides functions for generating random and regular graphs, graph visualization, centrality methods and much more.

This package provides a pure Python implementation of the Louvain algorithm for community detection in large networks.

This package provides an implementation of the function bioFabric for creating scalable network digrams where nodes are represented by horizontal lines, and edges are represented by vertical lines.

QVGE is a multiplatform graph editor written in C++/Qt. Its main goal is to make possible visually edit two-dimensional graphs in a simple and intuitive way.

This package contains the Tachyon raytracer. It supports the typical ray tracer features, most of the common geometric primitives, shading and texturing modes, etc. It also supports less common features such as HDR image output, ambient occlusion lighting, and support for various triangle mesh and volumetric texture formats beneficial for molecular visualization.

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

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

BRDF Explorer is an application that allows the development and analysis of BRDF. It can load and plot analytic BRDF functions (coded as functions in OpenGL's GLSL shader language), measured material data from the MERL database, and anisotropic measured material data from MIT CSAIL. Graphs and visualizations update in real time as parameters are changed, making it a useful tool for evaluating and understanding different BRDFs (and other component functions).

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.

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

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.

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.

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

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.

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.

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.

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.
