Open Source BSD 3D Rendering Software

VirtualGL redirects 3D commands from a Unix/Linux OpenGL application onto a server-side GPU and converts the rendered 3D images into a video stream with which remote clients can interact to view and control the 3D application in real time.

Founded in 1997, FlightGear is developed by a worldwide group of volunteers, brought together by a shared ambition to create the most realistic flight simulator possible that is free to use, modify and distribute. FlightGear is used all over the world by desktop flight simulator enthusiasts, for research in universities and for interactive exhibits in museums. FlightGear features more than 400 aircraft, a worldwide scenery database, a multi-player environment, detailed sky modelling, a flexible and open aircraft modelling system, varied networking options, multiple display support, a powerful scripting language and an open architecture. Best of all, being open-source, the simulator is owned by the community and everyone is encouraged to contribute.

The OpenGL Extension Wrangler Library is a simple tool that helps C/C++ developers initialize extensions and write portable applications. GLEW currently supports a variety of operating systems, including Windows, Linux, Darwin, Irix, and Solaris.

Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export).

MeshLab, a mesh processing system, for user assisted editing, cleaning, filtering and rendering of large unstructured 3D triangular meshes (typical 3D scanning meshes). The system relies for mesh processing tasks on the gpl VCG library (vcg.sf.net).

The Irrlicht Engine is an open source high performance realtime 3D engine written and usable in C++. It is completely cross-platform, using D3D, OpenGL and its own software renderers.

Celestia is an application for real-time 3D visualization of space, with a detailed model of the solar system, over 100,000 stars, more than 10,000 galaxies, and an extension mechanism for adding more objects.

GLFW is an Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan development on the desktop. It provides a simple API for creating windows, contexts and surfaces, receiving input and events.

Art of Illusion is a full featured 3D modelling, rendering, and animation studio. It is written entirely in Java, and can run on almost any operating system.

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

for the latest release see either - https://github.com/OGRECave/ogre - https://github.com/OGRECave/ogre-next An efficient, object-oriented hardware accelerated 3D engine. It abstracts the differences between APIs and platforms and allows scene-oriented coding through an easy to use object model. Adaptable to multiple scene types (indoor, outdoor, whatever)

The Pure Data (short Pd) project on SourceForge unifies the extensions (or externals) written for the Pure Data Graphical Computer Music System written by Miller Puckette with contributions from many others.

FreeWRL is an Open Source, cross platform VRML2 and X3D compliant browser, with script, SAI and EAI support. Platforms supported: Linux and other Unix-style platforms; Mac OS/X; Windows. Support for mobile platforms (iOS, Android, QNX) is under development.

3D game engine and multiplayer/singleplayer FPS game

BRL-CAD is a powerful cross-platform constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing for rendering & geometric analyses, network distributed framebuffer support, image & signal-processing tools.

A graph-based procedural texture editor to create 2d seamless textures for real-time rendering applications.

React Adopt is a small TypeScript library for composing multiple React render-prop components into a cleaner interface. It was created to solve the problem of nested render-prop callbacks, which can make React code harder to read and maintain. The library provides a simple adopt method that combines results from a mapper into a single render function. It supports use cases involving multiple render-prop utilities, React Context consumers, custom render handling, mapper-based prop shaping, and inline composition. At only about 0.7 KB minified, it is intentionally small and focused. It is most useful in older or render-prop-heavy React codebases that need a cleaner composition pattern without introducing a larger state-management abstraction.

Pixie is a photorealistic renderer that uses a RenderMan-like interface. Features include programmable shading, motion blur, depth of field, raytracing, scan-line rendering, occlusion culling, global illumination, caustics ...

GtkGLExt is an OpenGL extension to GTK+. It provides additional GDK objects which support OpenGL rendering in GTK+, and GtkWidget API add-ons to make GTK+ widgets OpenGL-capable.

GLC_Player is a OpenGL Open Source 3D viewer used to view 3d models (COLLADA, 3DXML, OBJ 3DS STL OFF COFF Format) and to navigate easily in these models.

OpenVRML is a cross-platform VRML and X3D browser and C++ runtime library.

3DCellForge is an AI-powered 3D cell generation and exploration studio built as a polished browser prototype. It uses React, Vite, Three.js, React Three Fiber, Drei, and Framer Motion to create an interactive WebGL environment for exploring biological cell models. Users can rotate, zoom, inspect organelles, compare views, take notes, capture screenshots, and export or import GLB models. The project also supports optional image-to-3D generation through cloud providers and local backends, while keeping API keys on the server side instead of exposing them in the frontend bundle. It includes cached demo models so the experience can work without generating a new model every time. Overall, it is a creative research and education tool for visualizing cell structures in a more interactive way than static diagrams.

Tulip is an information visualization framework dedicated to the analysis and visualization of relational data. Tulip aims to provide the developer/user with a complete library/software, supporting the design of interactive information visualization
