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.

Leiden is a general algorithm for methods of community detection in large networks and is an extension of the Louvain algorithm. This package implements the Leiden algorithm in C++ and can be run on graphs of millions of nodes (as long as they can fit in memory).

The package provides a reference implementation of the linear time edge addition algorithm for embedding planar graphs and isolating planarity obstructions.

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

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

Graph-tool is an efficient Python module for manipulation and statistical analysis of graphs (a.k.a. networks). Contrary to most other Python modules with similar functionality, the core data structures and algorithms are implemented in C++, making extensive use of template metaprogramming, based heavily on the Boost Graph Library. This confers it a level of performance that is comparable (both in memory usage and computation time) to that of a pure C/C++ library.

This package provides tools for building and manipulating graphs in Python.

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.

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.

Imath is a C++ representation of 2D and 3D vectors and matrices and other mathematical objects, functions, and data types common in computer graphics applications, including the "half" 16-bit floating-point type.

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.

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

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.

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.

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.

AutoTrace is a utility for converting bitmap into vector graphics. It can trace outlines and midlines, effect color reduction or despeckling and has support for many input and output formats. It can be used with the autotrace utility or as a C library, libautotrace.

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

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

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.

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

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.

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.
