Free 3d modeler software for linux

Vertex 3D Model Assembler project is a polygon-based live-end modeller.

The Vertex 3D Model Assembler is a 3D modeller geared towards making high performance models for games and other live-end requirements.

It uses the V3D format to maximize efficiency with OpenGL rendering, and can view/edit any V3D hybrid data.

Umbrello UML Modeller is a Unified Modelling Language diagram programme for KDE.
Umbrello UML Modeller allows you to create diagrams of software and other systems in a standard format.
Our handbook gives a good introduction to Umbrello and UML modelling.

3D Pong project is a simple Xlib vector-based ping-pong game.
3D Pong is is a very small and fast ping-pong or handball game for one or two players. It uses simple 3D vector graphics in Xlib.
Multiple views are possible, and red/blue separation is available for users with 3D movie glasses.
Main features:
Game Play:
- 1 player against the computer
- 1 player in "handball" mode
- 2 players, networked
- User-defined gravity level
- With or without a deflective "net"
Display Modes:
- Red/Blue split mode for true 3D using 3D glasses!!!
- Six viewing positions:
- First Person POV from behind your paddle
- "Bleacher" view from the side of the game arenta.
- Above view.
- Freely rotatable mode (using the mouse)
- A dizzying "follow the ball" mode
- Follow the paddle mode

Plotting all 2D and 3D functions had never been so easy. Many samples are included.
Its also possible to print or export the plots in postscript format.
Main features:
- Plot any 2D or 3D parametric function
- Save and open parameters of a plot
- Print or export to postscript format
- Separate output and control windows to allow more working space
- Many samples included
- Zoom and axis control

Morcego is a 3D graph browser for viewing and navigating any graph-like structure. Examples of such structures include social networks, site maps, hierarchies, and genealogy trees. It currently only support simple graphs.
Morcego 3D network browser already integrated into TikiWiki. Morcego is not meant to provide a solution for the end user, but to be embedded in a Web application by developers. Its a Java applet that communicates with an XML-RPC server to load the graph that is displayed.
Enhancements:
- New configuration vars (check README for meaning):
- frictionConstant, new Float(0.4f));
- elasticConstant, new Float(0.5f));
- punctualElasticConstant, new Float(1f));
- eletrostaticConstant, new Float(1000f));
- springSize, new Float(100));
- nodeMass, new Float(5));
- nodeCharge, new Float(1));
- loadPageOnCenter, new Boolean(true));
These are not used anymore:
- originX
- originY
- originZ
- universeRadius
- maxNodeSpeed
- linkedNodesDistance Changes:
- [ADD] physical model to balance graph
- [ADD] support for description box on mouse over
- [ADD] Morcego and Arca logs, optional
- [ADD] support for different transport layers, only XmlprcTransport available by now [ADD] option to have camera distance relative to nearest node instead of center, default.
- [ADD] option to open target page on every navigation, default
- [MOD] nodes pop always behind center node, to avoid hanging while rendering very big nodes
- [FIX] graph instability in some cases

Turtle3D project is a scheme implementation of the Turtle, in 3D.

It is object oriented, so you can have many turtles in the drawing window.

A test program is included.
