Open Source C 3D Modeling Software

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.

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.

GTS provides a set of useful functions to deal with 3D surfaces meshed with interconnected triangles including collision detection, multiresolution models, constrained Delaunay triangulations and robust set operations (union, intersection, differences).

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

The Open-Source PyMOL repository has been moved to github: https://github.com/schrodinger/pymol-open-source We still use the pymol-users mailing list here on sourceforge. Please subscribe for community support: https://pymol.org/maillist (Note: SourceForge email newsletter and special offers are optional and can be unchecked) The PyMOL community wiki has its own home: https://pymolwiki.org/

GLE is a library of C functions that draw extruded surfaces, including surfaces of revolution, sweeps, tubes, polycones, polycylinders and helicoids. GLE uses the OpenGL(R) API to perform the actual rendering.

SaVi - simulate Starlink, Iridium, Globalstar, O3b, GPS, Galileo and other satellite constellations, modify them, or design your own. Requires Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.

This repository is now frozen. The latest version of the RepRap project can be found at https://github.com/reprap.

Virtual Lego building for the Macintosh.

Geomorph is a height field generator and editor for Linux

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.

Ayam is a free 3D modelling environment for the RenderMan interface.

Varkon is a very powerful parametric 2D/3D CAD, modeling and application development tool for engineering, design, architecture, etc. It does 2D drafting, 2D and 3D modeling, sculptured surface modeling, and even animations. See our website for details.

CsGL is OpenGL for the .Net Framework, providing support for OpenGL 1.1 - 1.4 and numerous extensions.

GLOSS is a lightweight 3D modeler / animator / renderer for GNU/Linux or Windows platforms. GLOSS is programmed in C/GTK3.

xcruiser aims to provide 3D VR-like interface to UN*X filesystem. It displays directories as galaxies, files as planets (of various properties depending on its attributes) and symlinks as wormholes. You can fly through cyberspace created from these.

What can this do? Generte 3D Terrain Procedrally Export Terrain mesh as OBJ You can write and test your own shaders An Inbuilt IDE for shaders Test under different lighting A 3D viewer A Node based as well as Layer based workflow Save the project(custom .terr3d files) Hieght map visualizer in node editor Wireframe mode Custom Lighiting Customizable Geometry Shaders included in rendering pipeline Skyboxes Multithreded Mesh Generation Expected Goals for Version 3 Add a lot more Nodes Export to heightmaps(both PNG and also custom format) Node based procedural texture editing Custom Skyboxes Completely usable 3D procedural modelling and texturing pipeline Fix as many bugs I can find Things that may be added Wren scripting to add custom algotrithms Procedural grass and foliage Fix more bugs!

3D multiplayer realtime game with separately packaged 3D graphics middleware layer built on OpenGL. Runs on Linux, Win32, Mac OSX, Android - OpenGL/GLES 2.0 or later required

PovMorpheus is programm for morphing between two or more PovRay files. It is programm for generating intermediate files for animation. For example you can take two files with nurbs patches and to make interpolation with PovMorpheus.

The aim was to write a basic CAD system in windows using C. The system would have a plugin architecture which would allow the CAD system to be programmable.

Kludge3d is a simple 3d editor, in the spirit of Worldcraft or Milkshape. It is the offspring of several other (presumably abandoned) GTK-based editors, with the best features taken from each. As the name implies, kludge3d is exactly that - a kludge.

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.

A robotic DIY styrofoam cutter consisting of one rotational and two translational axes. It cuts a variety of shapes out of styrofoam-like materials using a hot wire. This project documents the necessary hardware and software parts. Don't miss the follow-up project at http://raumschaum.org Its goal is to further develop hardware and software into an user friendly application.

mesh2hmap is a simple command line tool for converting 3D meshes to raster heightmaps. This tool allows you to create terrains in your favourite 3D modeller and then easily convert to a heightmap image.

This is a viewer for ase (ASCII Scene Export) files. This code should be used to implement object loading in your own software (eg.: games).
