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

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

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).

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.

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.

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/

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!

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.

L3D is a 3D library for developing OpenGL applications under Linux. The library has a mail event loop with callbacks and Camera And Path Classes exist to produce cinematic camera movement. FPS entities are in construction

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

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

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.

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.

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.

LibAX is a skeletal animation library designed for use with Unreal Tournament PSK/PSA and Doom 3 md5mesh/md5anim. Optimized for use with vertex shaders and OpenGL VBOs, supports external memory management, no platform-specific code.

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.

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.

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.
