OpenCTM is a file format, a software library and a tool set for compression of 3D triangle meshes. The geometry is compressed to a fraction of comparable file formats (3DS, STL, COLLADA...), and the format is accessible through a simple, portable API

SaVi - simulate Starlink, Iridium, Globalstar, O3b, GPS, Galileo and other satellite constellations, modify them, or design your own. Requires Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.

GTS provides a set of useful functions to deal with 3D surfaces meshed with interconnected triangles including collision detection, multiresolution models, constrained Delaunay triangulations and robust set operations (union, intersection, differences).

The Open-Source PyMOL repository has been moved to github: https://github.com/schrodinger/pymol-open-source We still use the pymol-users mailing list here on sourceforge. Please subscribe for community support: https://pymol.org/maillist (Note: SourceForge email newsletter and special offers are optional and can be unchecked) The PyMOL community wiki has its own home: https://pymolwiki.org/

This repository is now frozen. The latest version of the RepRap project can be found at https://github.com/reprap.

CsGL is OpenGL for the .Net Framework, providing support for OpenGL 1.1 - 1.4 and numerous extensions.

Ayam is a free 3D modelling environment for the RenderMan interface.

Virtual Lego building for the Macintosh.

DeepMind Lab is a 3D learning environment based on id Software's Quake III Arena via ioquake3 and other open source software. DeepMind Lab provides a suite of challenging 3D navigation and puzzle-solving tasks for learning agents. Its primary purpose is to act as a testbed for research in artificial intelligence, especially deep reinforcement learning. If you use DeepMind Lab in your research and would like to cite the DeepMind Lab environment, we suggest you cite the DeepMind Lab paper. To enable compiler optimizations, pass the flag --compilation_mode=opt, or -c opt for short, to each bazel build, bazel test and bazel run command. The flag is omitted from the examples here for brevity, but it should be used for real training and evaluation where performance matters. DeepMind Lab ships with an example random agent in python/random_agent.py which can be used as a starting point for implementing a learning agent.

GLE is a library of C functions that draw extruded surfaces, including surfaces of revolution, sweeps, tubes, polycones, polycylinders and helicoids. GLE uses the OpenGL(R) API to perform the actual rendering.

Create 3D models easily in Win95,NT,XP,Vista,Win7 on all desktops, laptops and even netbooks without any 3D hardware acceleration. Supports 3DS, DXF, WRL, POV, ASC, spreadsheet & compressed files, extrude/sweep, mesh edit, parametric NURBS curves ...

What can this do? Generte 3D Terrain Procedrally Export Terrain mesh as OBJ You can write and test your own shaders An Inbuilt IDE for shaders Test under different lighting A 3D viewer A Node based as well as Layer based workflow Save the project(custom .terr3d files) Hieght map visualizer in node editor Wireframe mode Custom Lighiting Customizable Geometry Shaders included in rendering pipeline Skyboxes Multithreded Mesh Generation Expected Goals for Version 3 Add a lot more Nodes Export to heightmaps(both PNG and also custom format) Node based procedural texture editing Custom Skyboxes Completely usable 3D procedural modelling and texturing pipeline Fix as many bugs I can find Things that may be added Wren scripting to add custom algotrithms Procedural grass and foliage Fix more bugs!

A useful utility for producing stick figure animations, and then afterwords output the animations to formats such as 8-bit PNG files. Another goal is to output a x3d format world.

A parametric, feature-based, sketch-driven 3D CAD application, built around a geometrical constraint solving engine. Project is in early development stage. The FreeSG library (http://freesg.org/) is required.

Varkon is a very powerful parametric 2D/3D CAD, modeling and application development tool for engineering, design, architecture, etc. It does 2D drafting, 2D and 3D modeling, sculptured surface modeling, and even animations. See our website for details.

Geomorph is a height field generator and editor for Linux

GLOSS is a lightweight 3D modeler / animator / renderer for GNU/Linux or Windows platforms. GLOSS is programmed in C/GTK3.

OpenGI is a platform-independent C-library for parameterizing triangular meshes and creating Geometry Images from this parameterization.

A robotic DIY styrofoam cutter consisting of one rotational and two translational axes. It cuts a variety of shapes out of styrofoam-like materials using a hot wire. This project documents the necessary hardware and software parts. Don't miss the follow-up project at http://raumschaum.org Its goal is to further develop hardware and software into an user friendly application.

The extremely popular coolpowers series of plugins and shaders for Caligari trueSpace is now an open community project. From cel shading to blurred reflections, from glowing effects to landscape generation, there is something here for everyone. Power up

Command-line interface program that converts between IGES file and text file. IGES files are compatible with most of CAD systems. This program permits you to convert curves and points created in CAD program into coordinates in text file or you can do the opposite - convert text files into curves. It is especially suitable for curves described by hundreds of coordinates, e.g. airfoil contours of aircraft wings. Output filename is either out.txt or out.igs.

xcruiser aims to provide 3D VR-like interface to UN*X filesystem. It displays directories as galaxies, files as planets (of various properties depending on its attributes) and symlinks as wormholes. You can fly through cyberspace created from these.

mesh2hmap is a simple command line tool for converting 3D meshes to raster heightmaps. This tool allows you to create terrains in your favourite 3D modeller and then easily convert to a heightmap image.
