Open Source C 3D Modeling Software

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.

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/

Virtual Lego building for the Macintosh.

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.

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.

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

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

Geomorph is a height field generator and editor for Linux

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.

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.

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!

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

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.

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.

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.

Floyd is a collection of 3D libraries, mathematics and scene libraries and utilities. The main parts of it are geometry library Elea, OpenGL scene graph library Miletos and posing application Khayyam.

FltLib is a library written in portable C for reading the Multigen-Paradigm OpenFlight file format.

MagCAD is a set of tools for reconstructing 3D meshes from medical images such as MRI scans and ultra-sound. Resulting meshes are designed for CFD and visualisation

PyGTS is a python package used to construct, manipulate, and perform computations on triangulated surfaces. It is a hand-crafted and pythonic binding for the GNU Triangulated Surface (GTS) Library. THIS PROJECT IS NOT BEING MAINTAINED.

Stereograph is a stereogram generator that renders exclusively truecolor stereograms. It offers different effects to increase the quality of your artwork, also specials like transparency effects. GTKstereograph represents GUI to the current renderer.

A useful utility for producing stick figure animations, and then afterwords output the animations to formats such as 8-bit PNG files. Another goal is to output a x3d format world.
