Open Source 3D Modeling Software

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.

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

RawKee: an Open Source X3D File Format Plug-in for Alias' Maya 3D Authoring Software.

A suite of tools for processing and analyzing meshes and point clouds. 1) Ensuring that meshes are manifold, ie, "nice" 2) Simple smoothing/noise reduction 3) Bare-bones point cloud to mesh and robust normals for point clouds 4) Mesh simplification 5) Curvature calculation on meshes 6) Local shape descriptors on meshes

Coindesigner is a RAD environment to build 3D scenes based in openInventor, just using drag&drop and updating changes on the fly. An external multi platform viewer allows to distribute the scene without need of the RAD.

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.

Python scripts for importing and exporting OpenFlight files to and from Blender. OpenFlight is the native format of Creator, a 3D modelling package from MultiGen-Paradigm Inc. with a feature set that focuses on the real-time needs of the vis sim industry.

Python library for parsing, processing and linearising VRML97 files

GOAL: to make converter between various 3D file formats with some object manipulation capabilities

Xj3D is a project of the Web3D Consortium focused on creating a toolkit for VRML97 and X3D content written completely in Java. Xj3D has been produced and is maintained by Web3D Consortium members. Current status: active development with frequent updates. We have successfully ported the full codebase and history from the previous site to Sourceforge and are now following the Xj3D Evolution strategy. All open-source contributions are welcome. Further details are available at https://savage.nps.edu/Savage/developers.html#Xj3D

ACTC converts independent triangles into triangle strips or fans. You can approach a three times geometry speedup on OpenGL and Direct3D using these primitives.

The main download link is the installer for the compiled application. NOTE: The help files are accessible from within the application, from the main menu. The source code is bundled separately. Gimpel3D converts single images or frame sequences into stereoscopic 3D using a combination of traditional approaches and a proprietary projective modeling system. The user works in true proportional space where the scene can be viewed from any location. The scene is edited geometrically in space using tools specifically designed to work with the perspective projection of the image. This creates a virtual workspace that is intuitive for the user and proportionally accurate. NOTE: The entire codebase is currently in a single zip file (look under "Files"), and NOT in the sourceforge project repository..

A group of Blender (http://www.blender3d.org) enthusiasts sharing code for expanding the functionality of Blender. As Blender has been bought into Open Sourceness, this ancient utility is now ancient and likely useless.

C3A is a cross platform format for animated 3D geometry. Compact, fast, low bandwidth, and compatible with all current hardware/firmware; DirectX, OpenGL, XBox, PS2, 360, PS3, PSP, Wii, & DS.

So far there\\\'s a game called Racer (http://www.racer.nl/) and that\\\'s a car-racing game like NFS...They are using a format called *.DOF for their 3D-Models (cars and tracks), but only Windoz has a supported DOF-Converter (from ACE, 3DS or VRM

A simple library to load and save .[b]geo files in Houdini format. Be warned its functionality does not exceed loading and saving files and can only act as a rough template of how to work with .[b]geo files.

A small library made of one class (one method and one constructor) which takes two BufferedImages, the width and the height of the final image to produce a full anaglyph image from the images provided.

A library of POV-Ray definitions of LDraw parts to be used in conjunction with L3P and POV-Ray

Why do Archicad and Revit only share 30 or 40% of the global architectural sofware market ? Maybe because lots of small practices find these software unadapted to the way they work, and to their bank account. I think there's place for an open software that doesn't work like the existing. It will be simple in its tools and processes, and will have infinite capabilities. This will be possible by defining a logical structure. As I am an architect, and I know very little about programming, and wouldn't reach even in 10 years the necessary level to be able to write anything useful for this type of software, my part will be to bring ideas and coherence to this project. If you want to know some more : - go to the blog https://sourceforge.net/p/mollino/blog/ - write me a message ;) I speak french, german, english and italian. Martin Lucas

A command-line tool to convert polygon meshes to multi-triangulations

Voxelization is conversion of analytic graphic objects to representation by volumetric grids. The package provides for voxelization of various primitives. If objects have sharp edges, they are smoothed in order to prevent reconstruction artifacts.

Xi3D is an X3D renderer and browser for 3D Web content. It contains compliant parsers for VRML'97 types, a java scenegraph, XML bindings using SAX2, a content converter, full runtime and event model, DOM Level 2, vecmath

jSVR is an implementation of the Single view 3D reconstruction technique. It allows the recreation of 3D scenes from a single image. It provides a UI that navigates the user through a number of steps from a source image to a complete 3dmodel of the scene

Woa is a 3D reconstruction library, currently have not the ability to be a software, just a toy for somebody interesting in 3D reconstruction.
