Open Source C 3D Modeling Software for Mac

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.

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/

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

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.

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

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.

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

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

A simple library to load and save .[b]geo files in Houdini format. Be warned its functionality does not exceed loading and saving files and can only act as a rough template of how to work with .[b]geo files.

The 3ds to java converter is a 3ds loader for java3d. It uses the C-library lib3ds to convert files into a format that can easily be read into java, solving many of the bugs other 3ds loaders for java3d have.

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

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.

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.

Mac OS X and Windows OpenGL 3D Engine tools, content and code to create games and applications. Newton physics, OpenAL sound with OGG Vorbis, Lua, Revolution, written in C.

Woa is a 3D reconstruction library, currently have not the ability to be a software, just a toy for somebody interesting in 3D reconstruction.

A multi-platform graphical network analysis tool

3SUM aims to provide a powerful 2 to 3D programmable environment that allow editing several kind of contents and linking the relationships among Objective-C type. 3SUM sits on the top of AP3 framework which consit of 3D screen graph Objective-C API, C++ geometry math classes, basic mesh implementations, raster compositor and thread managements. AP3 also have a few foundation classes for data manipulation purpose, such as AAObject root which allows tagging object with selector-keyed arbitrarily typed bytes, or AAChunk, an equal-entry array which allows managing two or more binary streams as a single multi-field stream, or striding one stream into some, and some other partitioning abstractions. AP3 also provides a GUI system for NSOperation management, to provide the concurrency as much as everywhere-possible.

3D wireframe generation from a large dataset

BLIX is a cross-platform set of Python extension modules and Python scripts for Blender (www.blender.org). These scripts add camera calibration, 3D reconstruction and rigid body orientation to Blender.

A collection of tools to help in the creation of 3D graphics which are to assist in and improve various areas of the production pipeline in particular the creation and management of very large scale 3D graphics scenes.

A group of Blender (http://www.blender3d.org) enthusiasts sharing code for expanding the functionality of Blender. As Blender has been bought into Open Sourceness, this ancient utility is now ancient and likely useless.

BlueSphere is intended to become a functional 3d modeling tool similar to 3ds max and Maya. BlueSphere is mainly targeted at the modeling part of 3d ... but as development goes by, rendering will most likely also be implemented.
