Open Source C++ 3D Modeling Software for BSD

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.

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.

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

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.

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.

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.

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.

HARFANG 3D builds real-time 3D tools for industry professionals. Its software suite is tailored to developers, designers and engineers aiming to efficiently and seamlessly develop, implement & deploy 3D solutions (HMI, VR/AR, simulation, interactive 3D), regardless of development language or platform constraints. HARFANG Studio is the ideal 3D editor for creating real-time scenes & animations that match your design vision. It can manage the entire 3D graphics production workflow in a simple and optimized manner, without compromising the integration in other development environments. HARFANG Studio’s philosophy is in line with that of HARFANG 3D engine, a compliant, straightforward, fast & lightweight. Everything that runs in HARFANG Studio is compatible with our Framework and its supported coding languages. HARFANG Framework is an easy-to-adapt, cross-platform, multi-language, powerful and optimized 3D visualization engine written in C++ and accessible via an open API in C++.

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

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.

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.

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

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.

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.

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.

The Python Computer Graphics Kit is a collection of Python modules that contain the basic types and functions to be able to create 3D computer graphics images (focusing on Pixar's RenderMan interface).

tweak is a Maya plugin for tweaking a mesh in a natural workflow

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

Truevision is a 3D modeler for gnome and povray. It is still in an alpha developpement phase.

A C++ library to manipulate and create NURBS curves and surfaces.

B-Maxwell add-on offers seamless integration with Maxwell Render and Blender

High-level 3D graphics library. Supports retained and immediate mode rendering, an extensible file format, plug-in renderers, a wide range of high level geometries, hierarchical models, and a consistent and object-orientated API.

IVCon-TL can read and write a variety of 3D graphics file formats, converting from one to the other. Supported formats include 3DS, ASE, BYU, DXF, GMOD, HRC, IV, OBJ, OFF, POV, SMF, STL/STLA/STLB, TEC, TRI/TRIA/TRIB, UCD, VLA, WRL/VRML, XGL and more.

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.
