Gephi is free, open-source software for network visualization and analysis. It is available as a desktop application and as Gephi Lite in the browser. It includes algorithms for community detection, centrality measures and clustering, multiple layout algorithms, appearance customization and image exports. The source code is released under the GPL license.
Dia is free, open-source drawing software for creating structured diagrams. A Windows version is available as a free download, and the download page also provides packages for Mac OS X and Linux. The software is released under the GNU General Public License, GPLv2.
ntsc-rs is a free, open-source video effect that emulates analog TV and VHS artifacts. It is written in Rust and is available as a web app, a standalone application, and as a plugin for After Effects, Premiere, and OpenFX-compatible software.
FreeCAD is an open-source parametric 3D modeler for designing real-life objects of any size. It allows sketches of constrained 2D shapes as a base for building other objects. It is multiplatform and reads and writes many file formats. It is used for product design, mechanical engineering and architecture.
Quarkdown is an open-source, Markdown-based typesetting system for creating papers, presentations, knowledge bases and static websites. It offers a complete authoring experience with a reactive preview and scripting capabilities, and version 2.4 allows Markdown elements to be extended.
Physically Based is an open source database of physically based rendering values for CG artists, covering materials, light sources and cameras. It compiles values from publications, manufacturer documentation and user measurements, with each entry linked to at least one reference. The database is separate from the website and is built as an open API that can be integrated into applications as plug-ins, presets or web apps.
