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.

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.

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.

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

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.

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.

ASLI (A Simple Lattice Infiller) is a command-line tool that allows users to fill any 3D geometry with a functionally graded lattice. The lattice infill is constructed out of unit cells, described by implicit functions, whose type, size and feature can be varied locally to obtain the desired local properties.

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.

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

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.

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.

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).

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.

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.

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.

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.

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.

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

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.

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.

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

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.

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