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

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.

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.

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.

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.

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.

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

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

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.

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

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.

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).

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

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.

When a GPU renders triangle meshes, various stages of the GPU pipeline have to process vertex and index data. The efficiency of these stages depends on the data you feed them; this library provides algorithms to help optimize meshes for these stages, as well as algorithms to reduce the mesh complexity and storage overhead.

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.

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.

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.

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.

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.
