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.

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

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).

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/

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.

Virtual Lego building for the Macintosh.

DeepMind Lab is a 3D learning environment based on id Software's Quake III Arena via ioquake3 and other open source software. DeepMind Lab provides a suite of challenging 3D navigation and puzzle-solving tasks for learning agents. Its primary purpose is to act as a testbed for research in artificial intelligence, especially deep reinforcement learning. If you use DeepMind Lab in your research and would like to cite the DeepMind Lab environment, we suggest you cite the DeepMind Lab paper. To enable compiler optimizations, pass the flag --compilation_mode=opt, or -c opt for short, to each bazel build, bazel test and bazel run command. The flag is omitted from the examples here for brevity, but it should be used for real training and evaluation where performance matters. DeepMind Lab ships with an example random agent in python/random_agent.py which can be used as a starting point for implementing a learning agent.

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

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.

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.

Geomorph is a height field generator and editor for Linux

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!

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.

OpenGI is a platform-independent C-library for parameterizing triangular meshes and creating Geometry Images from this parameterization.

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.

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.

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.

ACTC converts independent triangles into triangle strips or fans. You can approach a three times geometry speedup on OpenGL and Direct3D using these primitives.

This is a program to view BvhFiles (a Motion capture format). In a nutshell, it shows 3D animated characters. It uses OpenGL. Ceci est un programme permettant de lire les fichiers Bvh (un format de motion capture). Il montre des personnages animés en 3D

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

Driver support for 3D Controller Hardware. We hope to support SDL Input, DirectInput, and other major controller API's including game consoles and embedded systems.

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.

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

Easy-to-use freeform sketch-based 3D modeler based on the paper by T. Igarashi et al, "Teddy: A Sketching Interface for 3D Freeform Design."
