Open Source C++ 3D Rendering Software for Linux

The OpenGL Extension Wrangler Library is a simple tool that helps C/C++ developers initialize extensions and write portable applications. GLEW currently supports a variety of operating systems, including Windows, Linux, Darwin, Irix, and Solaris.

The Irrlicht Engine is an open source high performance realtime 3D engine written and usable in C++. It is completely cross-platform, using D3D, OpenGL and its own software renderers.

Filament is a real-time physically-based renderer written in C++. It is mobile-first, but also multi-platform. We are very conscientious about keeping Filament small, fast to load, and focused on rendering. For example, Filament does not compile materials at run time. Instead, we provide a command line tool (matc) that does this offline. Filament is a physically based rendering (PBR) engine for Android. The goal of Filament is to offer a set of tools and APIs for Android developers that will enable them to create high quality 2D and 3D rendering with ease. For both artists and developers, our system will rely on as few parameters as possible to reduce trial and error and allow users to quickly master the material model. A physically based approach must not preclude non-realistic rendering. User interfaces for instance will need unlit materials. Our primary goal is to design and implement a rendering system able to perform efficiently on mobile platforms.

Open3D is an open-source library that supports rapid development of software that deals with 3D data. The Open3D frontend exposes a set of carefully selected data structures and algorithms in both C++ and Python. The backend is highly optimized and is set up for parallelization. Open3D was developed from a clean slate with a small and carefully considered set of dependencies. It can be set up on different platforms and compiled from source with minimal effort. The code is clean, consistently styled, and maintained via a clear code review mechanism. Open3D has been used in a number of published research projects and is actively deployed in the cloud. We welcome contributions from the open-source community. GCC 5.X and later on Linux. XCode 10+ and later on OS X 10.14+. Visual Studio 2019 and later on Windows.

GtkGLExt is an OpenGL extension to GTK+. It provides additional GDK objects which support OpenGL rendering in GTK+, and GtkWidget API add-ons to make GTK+ widgets OpenGL-capable.

Crystal Space is an Open Source 3D SDK for Unix, Windows, and MacOS/X. It renders with OpenGL and features GLSL shaders, CG shaders, deferred rendering, dynamic shadows, bullet based physics library, terrain engine, skeleton based animation meshes, exporter for Blender, portals, etc...

The SoftPixel Engine is an OpenSource high level realtime 3D engine for C++ (GNU C++ & VisualC++). It supports Direct3D11, Direct3D9, OpenGL 1.1 - 4.1, OpenGL|ES 1.1 and OpenGL|ES 2.0 and runs on Windows, Linux, Android and iOS.

The Perl OpenGL 2 module provides bindings to the modern OpenGL APIs for use from the perl language.

Thatcher Ulrich's game engine testbed. A motley collection of experimental and not-so-experimental game- and graphics-oriented code. Public domain!

QuesoGLC is a free implementation of the OpenGL Character Renderer. QuesoGLC is based on the FreeType library, provides Unicode support, and is designed to be easily ported to any platform that supports both FreeType and the OpenGL API.

GLC_lib is a C++ library for high performance 3D application based on OpenGL and QT4 GUI. Some GLC_lib features : Supported file format : 3DS, OBJ, COLLADA, 3DXML, OFF, STL. Easy view manipulation, Level of detail, shaders...

Tcl3D offers the 3D functionality of OpenGL and other 3D libraries at the Tcl scripting level.

The glVertex library emulates the legacy OpenGL API, which has been deprecated in OpenGL core profiles. It is also a convenience wrapper around GLSL shaders, VBOs and FBOs.

NeoEngine is an Open Source platform independent 3D game engine written in C++

BuGLe combines a graphical OpenGL debugger with a selection of filters on the OpenGL command stream. The debugger allows viewing of state, textures, framebuffers and shaders, while the filters allow for logging, error checking, video capture and more.

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.

A template library which provides a set of modular, generic, and reasonably efficient implementations of common raytracing algorithms.

This project has moved to GitHub: https://github.com/ubershader/GLSlayer OpenGL Sanity Layer is an object-oriented 3D graphics API on top of OpenGL written in C++. It is designed not just to provide an encapsulation of OpenGL objects, but to provide a cleaner and more streamlined interface similar to Direct3D and hide some of OpenGL's weak spots such as bind-to-edit semantics, multiple stage object creation, unavailability of platform independent initialization and loading of extensions to expose features. With GLSlayer it is easy to create a rendering context just by filling a structure and calling a function. All extensions needed to expose features for requested OpenGL version are loaded automatically. The code needed to create, setup and use objects is reduced and made intuitive. It supports OpenGL versions from 3.3 to 4.3, only forward compatible contexts.

Sh is a predecessor to the RapidMind Multi-core Development Platform, a metaprogramming language for programmable GPUs. It is the result of research at the University of Waterloo Computer Graphics Lab.

sql2diagram converts sql scripts to diagrams in the XML format dia, which can be viewed and further maintained with the dia drawing program. It is a good help for the documentation of a database structure. It provides HTML output as well.

2licht's aim is to provide a collection of wrappers for the popular Irrlicht Engine (http://irrlicht.sf.net/). It is still in development; the first wrappers to be released will be the C and Object Pascal interface; followed by a .NET library.

AllegRT is a 3D engine for making games based on 3D realtime raytracing for realistic results. It is based on and designed to work with Allegro.

AllegroGL is a small library intended to allow Allegro applications to use OpenGL in Unix, Windows, Mac OS X and DOS.
