PHIGS (Programmer's Hierarchical Interactive Graphics System)
PHIGS is an API standard for rendering 3D computer graphics. During the 1990's OpenGL became a more popular 3D API for professionals, and it still is today. PHIGS remains to be widely used in the film industry. Open PHIGS uses OpenGL for rendering graphics rather than implementing it's own abstraction layer to the graphics hardware, or using the PHIGS Extension to X (PEX). The reason for doing so is that today every graphics card manufacturer provides their own OpenGL implementation, which takes full advantage of the accelerated drawing capabilities in the hardware. PHIGS is a higher level API than OpenGL that works with a hierarchical scene graph. Models are built up in a Centralized Structure Store (CSS), a database containing the drawing primitives and their attributes (color, line style, etc.). CSSes cand be shared among a number of views, known under PHIGS as a workstation. PHIGS is defined by the ISO standards ISO/IEC 9592 & 9593. Open PHIGS provides a library for C.
Open-source, cross-platform 3D rendering engine for .NET and Mono. The Axiom Engine is a high-performance C# port of the powerful OGRE engine and provides full support for DirectX, OpenGL and XNA on Windows, Linux, Android, iPhone and Windows Phone.
The "Kambi VRML game engine" is renamed to "Castle Game Engine" (short name castle-engine). For commits and all current information see castle-engine project.
GTO is a file format whose primary usage is storage of static geometric data, though it can be used to store just about anything.
Equalizer is the standard middleware to create parallel OpenGL-based applications. Please visit https://github.com/Eyescale for current development information.
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.
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.
The simple graphics system (SGS) is a basic z-buffer based polygon rasterizer library.
