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.

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

Highly optimized 2D|3D math library, also known as OpenGL Mathematics (glm) for `C`. cglm provides lot of utils to help math operations to be fast and quick to write. It is community-friendly, feel free to bring any issues, bugs you faced. Almost all functions (inline versions) and parameters are documented inside the corresponding headers. OpenGL-related functions are dropped to make this lib platform/third-party independent. Make sure you have the latest version and feel free to report bugs, troubles. Euler angles was implemented in reverse order (extrinsic) it was fixed, now they are intrinsic. Make sure that you have the latest version. vec4 and mat4 variables must be aligned. (There will be unaligned versions later). cglm doesn't alloc any memory on heap. So it doesn't provide any allocator. You should alloc memory for out parameters too if you pass pointer of memory location.

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).

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

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.

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.

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.

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.

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.

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!

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

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

Main task of this project is to provide java3d scene loader for Bioware Neverwinter Nights(c) game models. It also covers some utilities built on top of it - animation preview, model optimalization and convertion, skinning preview etc.

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.

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.

TactileImage is a simple cross platform 2D-to-3D converter (currently jpeg to stl). It enables a blind person to "see" (to feel by a tip of a finger) the images - when printed on 3D printer. It could also be used for creation of terrain in 3D games

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
