a parametric 3D CAD modeler
WARNING: FreeCAD has moved! FreeCAD code and release files are now hosted on github at https://github.com/FreeCAD/FreeCAD Only older files and code are available 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.
Open Source Solid Modeling CAD
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.
K-3D is the free (as in freedom) 3d modeling, animation, and rendering system.
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.
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.
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.
Fractal planet and terrain generator
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.
Ayam is a free 3D modelling environment for the RenderMan interface.
The 3D Toolkit provides algorithms and methods to process 3D point clouds. In includes automatic precise registration (6D simultaneous localization and mapping, 6D SLAM) and other tools, e.g., a fast 3D viewer, plane extraction software, etc.
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
3D modeller that uses OpenGL on many platforms. Usability is a key design goal of this project, as is platform portability. The UI will be done with Qt.
GOAL: to make converter between various 3D file formats with some object manipulation capabilities
lignumCAD is a solid modeling tool oriented towards the design of furniture.
Freecloth is a free, open-source cloth simulation tool for use in cloth simulation research, and to help in production of feature films or games using cloth. The idea is similar to Maya Cloth: a tool to create clothing for digital characters.
OSGEdit is an editor of scenes for the library OpenSceneGraph, which provides an open sourced scenegraph for games, scientific applications and real-time simulations, among others.
A C++ API to work with manifold triangle meshes.
Cuts 3D objects from polystyrene foam (EPS/XPS)
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.
i3D-converter creates a 3D representation from a couple of images (or a pair of stereo images). This program also performs other Computer Vision operations such as, edge and corner detection, image filtering, getting geometric shapes,...
3D rendering and scene graph library
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.
Alliance Productions was started in early 2000 by Kazan as a publishng name for his utilities and campaign for FreeSpace 2. Now it has evolved into the publishing name for all projects started by him.
An implementation of generative grammars and turtle graphics. The grammars (currently only Lindenmayer systems) are used to produce descriptions of graphical images, and the turtle is used to display them in several forms, such as bitmap, PostScript or
