Free 3d software for linux

glTron project is a tron-like game with a 3D view.

glTron is a tron-like lightcycle game with a nice 3D perspective. 3D acceleration is recommended.

K-3D is the free-as-in-freedom 3D modeling, animation, and rendering system for GNU / Linux, Posix, and Win32 operating systems. K-3D features a robust, object-oriented plugin architecture, designed to scale to the needs of professional artists, and is designed from-the-ground-up to generate motion-picture-quality animation using RenderMan-compliant render engines. We strongly recommend the Aqsis render engine for use with K-3D.
K-3Ds innovative interactive tutorial system will introduce you to basic use of the program. New tutorials can easily be recorded and shared with the rest of the community.
K-3D allows you to create and edit documents in multiple realtime OpenGL solid, shaded, texture-mapped views. You can even model, animate, and interact with animations while they play back for maximum productivity!
Main features:
- Camera: pan/tilt, zoom, dolly, modeling and tripod modes.
- Viewing Modes: Detailed selection of visible features.
- Hide / unhide geometry.
- Powerful scene graph procedual modeling with complete modeling history.
- Selection: Objects, meshes, faces, edges, patched, curves, point groups, point.
- Geometry types: Polygon, NURBS, subdivision, blobby.
- 3D Primitives: Cone, circle, cushion, cylinder, disk, grid, paraboloid, polyhedon, sphere, torus.
- Boolean modeling operations.
- Text: FreeType? support.
- Instantiation: Create duplicates without adding gemometry to the scene.
- Directed Acyclic Graph (DAG) allows arbitrary dataflow - any object property can be connected to any other compatible property.
- Animate any value.
- Unlimited number of animation channels.
- Bezier curve channels.
- Animate modeling operations.
- Textures with 16-bit float bitdepth.
- Procedual RenderMan shaders.
- Full RenderMan Support: Aqsis, Pixie, BMRT, PRman, 3Delight, Render Dot C.
- Extensible support for alternate render engines and models: YafRay.
- Render OpenGL previews to disk.
- Python engine (preferred for new script development).
- K3DScript engine (minimal scripting engine for tutorials / macros).
- JavaScript engine (legacy script engine).
- Support for alternate script engine plugins and environments.
- Basic 2D compositing.
- Bitdepth 16-bit float per channel.
- Geometry Formats: AC3D, ASCII Scene Export, Apple QuickDraw?3D, AutoCad, Ayam, DirectX?, GNU Triangulated Surfaces, Quake II, PDB, RenderMan Interface Bytestream, VRML, Wavefront ... (some of them depend on PLIB installation)
- Image Formats:
- JPEG (all platforms).
- PNG (all platforms).
- TIFF (all platforms).
- OpenEXR (requires optional OpenEXR plugin).
- BMP (requires optional ImageMagick? plugin).
- SUN (requires optional ImageMagick? plugin).
Enhancements:
- This release features major changes to the internal file-handling code to work correctly with files containing non-ASCII characters.
- Due to the sweeping changes needed to make this possible, this version is considered a "development" release, so users are encouraged to use this release for testing and feedback only.
- All users are strongly encouraged to upgrade to the 0.6 series of K-3D for its completely rewritten user interface, many new features, and significantly improved stability over 0.4.

XInvaders 3D project is a 3D Space Invaders clone for X11.

You are a lone star fighter facing endless waves of space aliens. Your sole objective is to shoot down as many aliens as you can.

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

The Wurld 3D Engine is yet another 3D gaming engine. It is light, fast, has minimal external requirements, and is still very immature. The project is Python scriptable, including support for generating models using 3D turtle graphics.
