Virtuelium is an open-source multi-spectral physically based ray-tracer developed to render the visual appearance of material and to be able to do multi-scaled simulations of light interactions.
The Parallel Compositing library enables developers to write scalable 3D graphics applications. The library does sort-last compositing, and works on both clusters and SMP machines. The API aims to be the MPI of parallel compositing.
Turkish Airborne Simulator is a 3D flight simulation. You can fly above the all earth surface or roam the earth with using mouse like Google Earth. TAsim is based on OpenSceneGraph and VirtualPlanetBuilder.
A free rendered GUI library providing windowing and widgets for the easy creation of HUDs for games. It supports themes/skinning, XML-based configuration, and works with any graphics API or rendering engine including Axiom, Irrlicht, and SDL.NET.
With Ingo Wald's permission, XFRT has been created to provide a free (LGPL), high-performance library that is application source-compatible with the OpenRT api .
MathGL++ is a class library for fast C++ maths for use in OpenGL C++ projects. Easy to use and similar to the OpenGL API. Matricies, Vectors, Quaternions, Linear polynomials with eigen systems are all going to be included.
Realtime 3D game/visualization engine, written in C++, scriptable through Tcl/Tk, Python and Lua. Supports D3D and OpenGL for rendering, runs under Linux and Windows.
A codebase for the construction of 3d online virtual worlds. Includes everything you need to make your own multiplayer online roleplaying game. All game rules are contained in plugins which can be written in easy scripting languages such as Python.
Extendable widget based GUI framework for 3D applications. Works with any graphics API or render engine. Comes with reference implementations for OpenGL and the Ogre rendering engine. Library is written in C++, aimed at game developers.
XEngine is a platform- and rendering-API-independent 3D engine for real-time visualization with support for programmable graphics pipeline architectures implemented in C++. Platforms: Windows, Linux. APIs: OpenGL 1.3+, Direct3D 8.1, Direct3D 9.0
The X3DToolKit is a developer's API that allows you to load X3D files into a logical graph. That graph can then be traversed and converted into your favorite Graphic Scenegraph or can be rendered using X3DTK's OpenGL scenegraph.
KAGEfx is a framework to load shader programs based on the OpenGL Shading Language contained within an XML file that holds descriptive metadata about the shader and to replace shader modules on the fly with respect to their level-of-detail metadata.
This project is working on an open source implementation of the OpenGL ES 2.x API. Note: This project is currently on hold until release of the new fixed function pipeline implementation.
Iupiter is a Java API using both a lot of new features available with JDK 1.4 and its JVM, and the open source library LWJGL which enables us to use native APIs such as OpenGL and OpenAL, or OS services for interfacing to mouse, keyboard and joypad.
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.
1st 3D game engine built in C# for .NET, Visual3D Engine's predecessor
The first 3D game engine built in C# for .NET, predecessor to the Visual3D Game Engine (https://www.poweraccess.net/visual3d-game-engine), an All-in-One Game Development Tool for Next-Gen 3D Games, MMOs, Simulations and Virtual Worlds powered by Microsoft XNA.
A 3D graphics engine for use in 3D games and other real-time rendering applications using managed code (C#) and the .NET framework and supporting both the OpenGL and Direct3D APIs
SGL is a cross-platform, C++, scene graph API for real-time visualization (e.g., vis-sim, gaming, scientific modelling, GIS apps). It manages all the data needed to render a 3D scene using OpenGL.
Klimt (formerly known as SoftGL) is a 3D library with a similiar API to that of OpenGL and OpenGL|ES, targeted for mobile devices. We are searching for developers. If you want to join send an email to the project leader.
The ion engine is a portable 3D graphics engine for C++. It completely abstracts the underlying API (both OpenGL and Direct3D are supported). Programmable hardware is fully supported.
