Open Source BSD 3D Modeling Software

This is an official mirror of FreeCAD. Code and release files are primarily hosted on https://github.com/FreeCAD/FreeCAD and mirrored here. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization. FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.

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).

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

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.

Regard3D is a free, multiplatform, open-source structure-from-motion application. It creates 3D models of objects, based on photographs from different angles.

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.

Importer library to import assets from different common 3D file formats such as Collada, Blend, Obj, X, 3DS, LWO, MD5, MD2, MD3, MDL, MS3D and a lot of other formats. The data is stored in an own in-memory data-format, which can be easily processed. www.open3mod.com/ is a 3D model viewer and exporter based on Assimp that is also Open Source.

Misfit Model 3D is an OpenGL-based 3D model editor. It supports multi-level undo, skeletal animations, texturing mapping, scripting, command-line batch processing, and a plugin system for adding new features. Complete online help is included.

GraphCalc is a very gui graphing calculator. It has been called a good replacement for a TI-85. It is a must for any high school math student.

This project is no longer valid. See vpython.org.

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

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).

Interactive application to generate and view random fractal planets and terrain with oceans, mountains, icecaps and rivers, then export them to POV-Ray format or Blender. Written in C++ using Qt and OpenGL.

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.

Arbaro is an implementation of the tree generating algorithm described in Jason Weber & Joseph Penn: Creation and Rendering of Realistic Trees

ngPlant is a plant modeling software package. ngPlant interactive tool can be used to create 3D models of different plants and trees. ngPlant software libraries can be used by developers in their 3D applications, or plant modeling plugins.

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/

Structure Synth generates 3D structures by specifying a design grammar. Even simple systems may generate surprising and complex structures. Structure Synth offers a graphical environment with multiple tabs, syntax highlighting, and OpenGL preview.

Extensible 3D (X3D) Graphics is a royalty-free International Standard for real-time interactive 3D graphics on the Web, providing unsurpassed interoperability for 3D communications on the Web. This project includes source for example X3D scene libraries and multiple X3D codebases produced by Web3D Consortium members. All open-source contributions are welcome.

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.

The B-processor will renew the digital building model by implementing the B-model based on subdividing the project-space in connected functional and constructional spaces – a model with dynamic abilities and possibilities for effective 3D detailing

Converts a raw digitized polygon mesh to a clean mesh where all the occurrences of a specific set of "defects" are corrected. Holes, self-intersections, degenerate and non-manifold elements are all replaced with valid configurations.

OGITOR is an attempt to build a general purpose editor to quickly create scenes which can then loaded in an OGRE application for both rapid prototyping purposes and also supplying a WYSWYG editor environment for OGRE.

Raytrace is designed to be a completely platform independant Raytracer which includes a Gui interface. Designed and written in Sun Microsystem's Java language.

surfit is an open source and free gridding and contouring software. surfit can do interpolation/approximation of points, contours and surfaces, can take fault lines and trend surfaces into account, can use inequalities and other conditions. Supports a lo
