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.
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.
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.
Simple CAD program
ZCAD is simple CAD program with dxf2000 file format support. Source code available here http://svn.shamangrad.net/zcad/trunk/
A Qt port of the GPL bvh editor "avimator" (http://www.avimator.com/). You can load / play / edit / create bvh files to animate 3D avatars with qavimator
First-person 3D building and elevator simulator
Skyscraper is a fully featured first-person 3D virtual building simulator, written in C++ and using the OGRE graphics engine (previous versions used Crystal Space). It's flagship feature is an elaborate and realistic elevator simulator.
Symbian 3D Engine Open Source - The EPOC Community Premier 3D Development
XMUD is a MMORPG implementation in Java. Players can extend the system by creating new objects. The game provides a 3D engine written in Java3D, Persistent state management, synchronization and networking subsystems. Compatible with NWN modules.
Geomorph is a height field generator and editor for Linux
OpenGL.NET is an OpenGL-Wrapper implemented in C# for the .NET-Framework. This binding should not be created by hand but by a WrapperGenerator, which is part of this project. The development takes place unter Linux with Mono.
DotsPlus is a way of integrating tactile captions into 3D CAD models for prototyping, tooling and manufacturing. The project is coded in C++ and supports at least the Alias|Maya plugin API and Open Inventor (Linux) and Coin3D (Linux/MacOS).
CSG for jMonkey
Expanded Constructive Solid Geometry support for jMonkey. CSG supports boolean operations on primitive shapes, building up a complex surface from the addition/subtraction of simple cubes, spheres, etc. Check out the jMonkeyCSG website for more details.
Toolkit for exporting/importing Maya scenes to/from OpenSceneGraph
NecJGui is an antennas design tool, interface for Numerical Electromagnetic Code. It allows easily making NEC input files, and viewing them in 3D. It also contains a version of the simulator, so it's complete IDE for full-wave EM simulation.
The Open Descent Foundation (ODF) is a community for developers, who want to help to create open source programs, tools, etc. for the famous games Descent1, -2 or -3. Everyone can join the ODF if he accepts the idea of writing open source programs.
Lhogho is planned to be a modern implementation of the Logo programming language providing reasonable compatibility with older Logos, 3D graphics in real time and user-friendly OOP support.
osgSceneMaker is 3D graphical tool for creating and preparing scenes to work in OpenSceneGraph. osgSceneMaker works on both Linux and Windows using wxWidgets and OpenGL.
Truevision is a 3D modeler for gnome and povray. It is still in an alpha developpement phase.
Architecture for POV-Ray. A set of macros for easy creation of walls, windows, doors, railings and other things useful for building creation.
Teara is a program to model terrain data in real time using OpenGL
KLevel is a heightfield modelling tool designed to mimic Leveller for Windows. It features an OpenGL preview and many brush-like tools.
Falmaidan (which in the Elventongue Sindarin means "maker of waves") is a program for realistically simulating the movement of fluids. It works as a preprocessor for POV-Ray scene files. The aim is to produce breathtaking animations one day.
This project is developing avionics for use in experimental aircraft. Systems under development with OpenGL include EFIS, NAV and EIS systems.
calder is a multi-platform sculpting software targetted for artists and home users. The main goal of the product is to maximize the user's sculpting experience on the computer.
The Poseidon project consists of the Poseidon 3D engine and a several tools (Ksenomorph 3D modeler, world editor, light and material editor, 2D sprite editor).
