gnuplot is a command-line and GUI program that can generate two- and three-dimensional plots of functions, data, and data fits. The program runs on all major computers and operating systems (Linux, Unix, Microsoft Windows, macOS, FreeDOS, and many others). Originally released in 1986, its listed authors are Thomas Williams, Colin Kelley, Russell Lang, Dave Kotz, John Campbell, Gershon Elber, Alexander Woo "and many others." Despite its name, this software is not part of the GNU Project.

OpenSCAD is a free software application for creating solid 3D computer-aided design (CAD) objects. It is a script-only based modeller that uses its own description language; the 3D preview can be manipulated interactively, but cannot be interactively modified in 3D. Instead, an OpenSCAD script specifies geometric primitives (such as spheres, boxes, cylinders, etc.) and defines how they are modified and combined (for instance by intersection, difference, envelope combination, or Minkowski sums) to render a 3D model. As such, the program performs constructive solid geometry (CSG). OpenSCAD is av

The Persistence of Vision Ray Tracer, most commonly acronymed as POV-Ray, is a cross-platform ray-tracing program that generates images from a text-based scene description. It was originally based on DKBTrace, written by David Kirk Buck and Aaron A. Collins for Amiga computers. There are also influences from the earlier Polyray raytracer because of contributions from its author, Alexander Enzmann. POV-Ray is free and open-source software, with the source code available under the AGPL-3.0-or-later license.

Object-Oriented Graphics Rendering Engine (OGRE) is a scene-oriented, real-time, open-source, 3D rendering engine.

jMonkeyEngine (abbreviated JME or jME) is an open-source and cross-platform game engine for developing 3D games written in Java. It can be used to write games for Windows, Linux, macOS, Raspberry Pi, Android, and iOS (currently in alpha testing). It uses Lightweight Java Game Library as its default renderer, and also supports another renderer based on Java OpenGL.

MakeHuman is a free and open source 3D computer graphics middleware designed for the prototyping of photorealistic humanoids. It is developed by a community of programmers, artists, and academics interested in 3D character modeling.

libGDX is a free and open-source game-development application framework written in the Java programming language with some C and C++ components for performance dependent code. It allows for the development of desktop and mobile games by using the same code base. It is cross-platform, supporting Windows, Linux, macOS, Android, iOS, BlackBerry and web browsers with WebGL support.

Panda3D is a game engine that includes graphics, audio, I/O, collision detection, and other abilities relevant to the creation of 3D games. Panda3D is free, open-source software under the revised BSD license.

O3D is an open-source (BSD license) JavaScript API created by Google for creating interactive 3D graphics applications that run in a web browser window or in a XUL desktop application. O3D may be crafted for use in any application area; however, it is geared towards games, advertisements, 3D model viewers, product demos, simulations, engineering applications, control and monitoring systems, and massive online virtual worlds. O3D is currently in Google's incubation lab, and was originally built as a web browser plugin. Since 2010, O3D is a JavaScript library implemented on top of WebGL.

Sketchfab is a 3D asset website used to publish, share, and discover 3D, VR and AR content. It provides a viewer based on the WebGL and WebXR technologies that allows users to display 3D models on the web, to be viewed on any mobile browser, desktop browser or Virtual Reality headset.

MeshLab is a 3D mesh processing software system that is oriented to the management and processing of unstructured large meshes and provides a set of tools for editing, cleaning, healing, inspecting, rendering, and converting these kinds of meshes. MeshLab is free and open-source software, subject to the requirements of the GNU General Public License (GPL), version 2 or later, and is used as both a complete package and a library powering other software. It is well known in the more technical fields of 3D development and data handling.

Blend4Web is a free and open source framework for creating and displaying interactive 3D computer graphics in web browsers.

S&box (pronounced Sandbox) is an upcoming open source video game development platform and engine by Facepunch Studios. It is built using a heavily modified Source 2 engine and will be released on April 28, 2026. S&box is intended to be a spiritual successor to ''Garry's Mod'' and is designed to allow users to create a variety of games and experiences.

OpenTK, also known as The Open Toolkit library, is a C# graphics library superseding the Tao Framework. It provides access to graphics tools contained in OpenGL, OpenCL, and OpenAL to a variety of CLR-based languages (C#, F#, etc.). Particularly, it is usable with any language utilizing either of the .NET Framework or Mono frameworks for versions prior to 4.0 and .NET Core 3.1 and up, continuing with .NET 5, for major version 4. In the upcoming version 5 previews Vulkan is also supported.
