- ADG: Automatic Drawing Generation
- The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a library providing a non-interactive canvas where you can put common CAD entities such as paths, xatches and quotes, to create your technical drawings. The final result can be displayed inside a GTK+ widget or exported to any cairo available format, such as PostScript and PDF documents or PNG and SVG images.
- 'Aalib' is a low level gfx library that works on any kind of terminal. It does not require graphics devices (in fact, no graphical output is possible), and is particularly useful for those with older hardware who do not want to worry about overloading their systems with graphical applications.
- 'Aewan' lets users create and edit ASCII art. Users move the cursor around with the arrow keys, "paint" characters by pressing the corresponding key, and choose foreground and background colors, and bold and blink attributes, with dialog boxes. They can also select, move, copy, and paste rectangular areas of the canvas. Aewan supports "intelligent" horizontal and vertical flipping (e.g., it converts "\" to "/", etc) and can work with multiple layers, turn transparency and visibility on and off for each layer, and change the order of the layers. Thus, each layer can be edited independently to generate a composite drawing. Layers can also be used as frames for an animation, thereby creating ASCII animations.
- 'Asymptote' is a script-based vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. It is a programming language, not just a graphics program, so it can use the best features of both scripts and GUIs. High-level graphics commands are implemented in the language itself, so they can be tailored to specific applications. Labels and equations are typeset with LaTeX for high-quality PostScript output.
- Autotrace is a program which converts bitmap images to vector images. It can import images in BMP, TGA, PNM, PPM, PGM, PBM and those supported by ImageMagick, and can output Postscript, svg, xfig, swf, pstoedit, emf, dxf, cgm, mif, p2e and sk
- Biggles is a Python module for the creation of publication-quality 2D scientific plots. Its features include an elegant, high-level interface, a simple TeX interpreter, and postscript, png, gif, svg, and x11 output formats.
- The goal of the CGAL Project is to provide easy access to efficient and reliable geometric algorithms in the form of a C++ library. CGAL is used in various areas needing geometric computation, such as: computer graphics, scientific visualization, computer aided design and modeling, geographic information systems, molecular biology, medical imaging, robotics and motion planning, mesh generation, numerical methods...
CGAL offers data structures and algorithms like triangulations (2D constrained triangulations and Delaunay triangulations in 2D and 3D), Voronoi diagrams (for 2D and 3D points, 2D additively weighted Voronoi diagrams, and segment Voronoi diagrams), Boolean operations on polygons and polyhedra, arrangements of curves and their applications (2D and 3D envelopes, Minkowski sums) mesh generation (2D Delaunay mesh generation and 3D surface mesh generation, skin surfaces), geometry processing (surface mesh simplification, subdivision and parameterization, as well as estimation of local differential properties, and approximation of ridges and umbilics), alpha shapes, convex hull algorithms (in 2D, 3D and dD), operations on polygons (straight skeleton and offset polygon), search structures (kd trees for nearest neighbor search, and range and segment trees), interpolation (natural neighbor interpolation and placement of streamlines), shape analysis, fitting, and distances (smallest enclosing sphere of points or spheres, smallest enclosing ellipsoid of points, principal component analysis), and kinetic data structures. All these data structures and algorithms operate on geometric objects like points and segments, and perform geometric tests on them. These objects and predicates are regrouped in CGAL Kernels.
- Cairo is a vector graphics library with cross-device output support. It currently supports the X Window System and in-memory image buffers as output targets. It is designed to produce identical output on all output media while taking advantage of display hardware acceleration when available (eg. through the X Render Extension). It provides a stateful user-level API with capabilities similar to the PDF 1.4 imaging model and provides operations including stroking and filling Bezier cubic splines, transforming and compositing translucent images, and antialiased text rendering.
- Multiplatform raster graphical editor enabling simultaneous drawing between users. It's written in Java and it is GPLv3 licenced. Project including several sub projects as server, painting framework, network library, desktop application and protocol design and documentation.
- 'ePiX', a collection of batch programs, creates mathematically accurate fgures, plots, and animations containing LaTeX typography. The input syntac is easy to learn. The output -- vector image files or LaTeX picture-like environments -- is expressly designed for use with LaTeX.
