K-3D is the free (as in freedom) 3d modeling, animation, and rendering system.

FREE!ship is a surface modeling program for designing ships yachts and boats. Subdivision surfaces are used rather than NURBS to give the designer the freedom to design ANY desired hullshape. Unfold surfaces, panel based hydrostatics, various exp formats

Milvus is an open-source vector database built to power embedding similarity search and AI applications. Milvus makes unstructured data search more accessible, and provides a consistent user experience regardless of the deployment environment. Milvus 2.0 is a cloud-native vector database with storage and computation separated by design. All components in this refactored version of Milvus are stateless to enhance elasticity and flexibility. Average latency measured in milliseconds on trillion vector datasets. Rich APIs designed for data science workflows. Consistent user experience across laptop, local cluster, and cloud. Embed real-time search and analytics into virtually any application. Milvus’ built-in replication and failover/failback features ensure data and applications can maintain business continuity in the event of a disruption. Component-level scalability makes it possible to scale up and down on demand.

Inspired by and built on top of open-source projects. RAWGraphs is open to the community for contributions. Almost 30 visual models to visualize quantities, hierarchies, and time series and find insights in your data. Even though RAWGraphs is a web app, the data you insert will be processed only by your web browser. Save your project, or export it as a vector or raster image. Edit it within your favorite software. RAWGraphs is an open source data visualization framework built with the goal of making the visual representation of complex data easy for everyone. Primarily conceived as a tool for designers and vis geeks, RAWGraphs aims at providing a missing link between spreadsheet applications (e.g. Microsoft Excel, Apple Numbers, OpenRefine) and vector graphics editors (e.g. Adobe Illustrator, Inkscape, Figma). The project, led and maintained by the DensityDesign Research Lab (Politecnico di Milano) was released publicly in 2013.

JaxoDraw is a tool to generate Feynman diagrams in a mouse click-and-drag fashion. Graphs can be exported to a variety of graphics formats and arbitrary latex code can be used for labels to produce high-quality publishing-style figures.

Drawj2d creates technical line drawings using a descriptive language. It writes pdf, svg, eps, emf and dxf vector graphics or png images. It runs on all platforms that run Java. It is inspired by Asymptote but with a tcl-like syntax and 2D only.

JHotDraw is a two-dimensional graphics framework for structured drawing editors that is written in Java. It is based on Erich Gamma's JHotDraw, which is copyright 1996, 1997 by IFA Informatik and Erich Gamma.

This project provides a library of easy to use 2D graphics editor tools and a functional and extendable stand-alone graphics editor.

Whyteboard is a painting whiteboard application for Linux and Windows, that allows the annotation of PDF and PostScript documents, and image files with common drawing tools.

Varkon.Org is a resource site for users of the Varkon parametric CAD and modeling system. This site is a mirror and archive for the Varkon.Org site. You can find all versions of modules for use with Varkon on this mirror site. See the website for info.

TouchGraph provides a set of interfaces for graph visualization using force-based layout and focus+context techniques. For now only older code is available, but we are planning to release new versions as well.

Free 3D Acropolis is a model 3D in hight resolution of the Acropolis of Athens shortly after its construction.

InkPlot is an extension (plugin) for the SVG Editor Inkscape to insert graphs from Gnuplot. It allows you to - preview the graph - add it as SVG into Inkscape - edit already generated graphs - use a preamble file for reusable style and commands - customize default settings in a config file

Please see laidout.org for current code and download location. Laidout is desktop publishing and imposition software for Linux, particularly for multipage, cut and folded booklets, with page sizes that don't even have to be rectangular. Bug reports welcome!

Delphi & Kylix Components project - Components & Classes for graphic representation of objects (for Visio-Like software). The purpose is to build easy-access librairies for building IDEF,OMT,UML,E/R,Graphcet,Organigram applications.

PLOT_PSXPS provides a set of graphic functions that allows the generation of PostScript files (and runtime viewing with X) from C/C++ programs. A page can contain points, lines, arcs, ellipses, circles, boxes, text, included EPS files and a lot more.

The aim of this project is to export the xfigure library (.xfig) to provide free stencils/shapes for kivio (.sml) and OpenOffice.org/StarOffice (.sxd,.wmf). The images (over 900) can be used in the OpenOffice.org`s Gallery.

A library which can be used to build a vector graphic application.

BizDiag V1.9 All new version (based on Mono and GTK#, developed with MonoDevelop 2.4.1). BizDiag V1.0, V1.1, V1.2 Business graphics diagramming application + diagram editor library for vector graphics (based on Piccolo2D from University of Maryland, .NET and Windows.Forms developed with Visual Studio 2008). Supports browser-enabled special SVG file format for import and export and customizable shape library.

ConnectCode Software Box Shot Maker creates realistic images of 3D boxes for your softwares using three image files. You can adjust the box orientation, box and camera position. Despite being opensource, the tool delivers professional results.
