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.
Importer library to import assets from different common 3D file formats such as Collada, Blend, Obj, X, 3DS, LWO, MD5, MD2, MD3, MDL, MS3D and a lot of other formats. The data is stored in an own in-memory data-format, which can be easily processed. www.open3mod.com/ is a 3D model viewer and exporter based on Assimp that is also Open Source.
PyFFI is a Python library for processing block structured binary files. Supports NetImmerse/Gamebryo (NIF, KFM), Crytek (CGF), FaceGen (EGM), DDS, and TGA. Includes 3D tools (stripifier, tangent space), utility scripts, and a file editor QSkope.
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.
Ayam is a free 3D modelling environment for the RenderMan interface.
ColladaCGF enables exporting 3D models into Crysis, using Crytek's resource compiler and Blender/Maya's Collada exporters. Import is partly supported as well, via the Python File Format Interface.
Earth orbits and coverage display in 3D on your laptop.
SaVi - simulate Iridium, Globalstar, O3b, Sirius Radio, GPS, Galileo and other satellite constellations, modify them, or design your own. Uses Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.
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.
Planet and Terrain generator written in Java. Generation 16 bit greyscale PNG bitmap textures as a basis for displacement for planetary bodies and terrain. Generation of Wavefront and POV meshes and Terragen Terrain files
Varkon.Org is a resource site for users of the Varkon parametric CAD and modeling system. This site is a mirror and archive for the Varkon.Org site. You can find all versions of modules for use with Varkon on this mirror site. See the website for info.
ACTC converts independent triangles into triangle strips or fans. You can approach a three times geometry speedup on OpenGL and Direct3D using these primitives.
NOTE: As of August 2006, development of this COLLADA plugin has migrated into the official OpenSceneGraph repository, so this SourceForge project is frozen for historical reference only. See http://openscenegraph.org/
X3D is the open-standard format for 3D graphics scenes on the Web.
Extensible 3D (X3D) Graphics is a royalty-free International Standard for real-time interactive 3D graphics on the Web, providing unsurpassed interoperability for 3D communications on the Web. This project includes source for example X3D scene libraries and multiple X3D codebases produced by Web3D Consortium members. All open-source contributions are welcome.
A parametric, feature-based, sketch-driven 3D CAD application, built around a geometrical constraint solving engine. Project is in early development stage. The FreeSG library (http://freesg.org/) is required.
MonkeyWorld3D is a scene graph editor for the jMonkeyEngine (jME). You can edit scene elements, terrain, physics and animations. Our aim is to make a WYSIWYP (What you see is what you play) game editor.
AS OF 2015-10, HIS REPO IS FROZEN. Any future development will occur at https://github.com/mew-cx/osgtoy A grabbag of various experimental/maybe-useful "toys" for the OpenSceneGraph, such as examples, experiments, utilities, file importer plugins, and pseudoloaders. See also: http://openscenegraph.org/ http://mew.cx/osg/
A graphics program which allows to model and render 3D objects and scenes.
A Java based molecular modeling program. Has support for generating movies by interpolating between given positions, interactive display and manipulation of atoms and bonds, and dynamic modeling of substance formation.
Python library for parsing, processing and linearising VRML97 files
This modeler is an opensource Eclipse RCP product intended to be augmented by the community via plug-ins (done in the RCP way).
The Baja Engine is an advanced, easy to use 3D game engine for Mac, Windows, and Linux. Baja provides world-class 3D, 2D, audio, shader, scripting, editing, special effect, animation, and networking capabilities.
A utility to help create animations in POV-Ray, a free raytracer. In your POV-Ray code, insert variable names instead of numbers for any values which may change. An #include file is generated based on keyframes which will fill in those variabes.
A portable, high-level 3D engine with an emphasis on generality. So far it is mainly used in CAD applications in need of geometrical constraint solving and other geometrical methods. FreeSG is designed as an integrable component and not a framework.
A map editor for games which use deriatives of the .MAP format e.g. Quake(I-III) engine; Torque engine. Multi-title compatability via export plugins, plus non-proprietary XML output for editor-specific 'plan' export. Java / OpenGL-based.
Geomatrix, collection of C/C++ libraries to be used for symbolic description of n-dimensional geometric models. Operates internally with a representation that constructs complex objects based on primitives, allowing loss-less modifcation of models.
