Leiden is a general algorithm for methods of community detection in large networks and is an extension of the Louvain algorithm. This packages provides a Python wrapper to the C++ implementation.

plantri and fullgen (contained in the same package) are programs for the generation of certain types of planar graphs. Graphs are generated in such a way that exactly one member of each isomorphism class is output without the need for storing them.

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

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

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.

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

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.

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.

This package implements the Louvain algorithm for community detection in C++ and exposes it to Python. Besides the relative flexibility of the implementation, it also scales well, and can be run on graphs of millions of nodes (as long as they can fit in memory). The core function is find_partition which finds the optimal partition using the louvain algorithm for a number of different methods.

Mscgen is a small program that parses Message Sequence Chart descriptions and produces PNG, SVG, EPS or server side image maps (ismaps) as the output. Message Sequence Charts (MSCs) are a way of representing entities and interactions over some time period and are often used in combination with SDL. MSCs are popular in Telecoms to specify how protocols operate although MSCs need not be complicated to create or use. Mscgen aims to provide a simple text language that is clear to create, edit and understand, which can also be transformed into common image formats for display or printing.

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

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.

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.

This package contains OpenXR headers, as well as source code and build scripts for the OpenXR loader.

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.

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

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

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.

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.

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.

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.

Mmg is a collection of applications and libraries for bidimensional and tridimensional surface and volume remeshing. It consists of:

• the mmg2d application and library: mesh generation from a set of edges, adaptation and optimization of a bidimensional triangulation and isovalue discretization;

• the mmgs application and library: adaptation and optimization of a surface triangulation and isovalue discretization;

• the mmg3d application and library: adaptation and optimization of a tetrahedral mesh, isovalue discretization and Lagrangian movement;

• the mmg library gathering the mmg2d, mmgs and mmg3d libraries.

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.

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