  Fahrenheit graphics API
Fahrenheit was an effort to create a unified API for 3D computer graphics.
However the hardware was not ready at the time, and the tile based API was not appropriate for the scene graph based video cards that were just starting to become common.
Fahrenheit would include a new scene graph based API that would work on top of either existing system, with no performance penalty when converting down to the underlying system.

 Fahrenheit graphics API - One Language   (Site not responding. Last check: 2007-10-19)
Fahrenheit was an effort to create a unified high-level API for 3D computer graphics.
SGI was to provide the primary "mid-sized" API used in most applications, Fahrenheit Scene Graph, as well as a modified version for handling very large models from CAD applications, Fahrenheit Large Model.
SGI saw Fahrenheit as an exit strategy; once complete they would be able to move to a PC-based lineup while still offering the best development tools for a now universal API.

 Wikinfo | Fahrenheit
In the Fahrenheit scale of temperature, the freezing point of water is 32 degrees, and the boiling point is 212 degrees, conveniently placing the boiling and melting points of water 180 degrees apart.
From this you can also determine that a degree Fahrenheit is 5/9ths of a kelvin or degree Celsius, and -40 degrees Fahrenheit is equal to -40 degrees Celsius.
Fahrenheit established zero degrees as the temperature at which an equal mixture of ice and salt melts (some say he took that fixed mixture of ice and salt that produced the lowest temperature); and ninety-six degrees as the temperature of a healthy human body.

Fahrenheit is the name of the collaborative project between Silicon Graphics and Microsoft for developing a suite of high-performance visualization technologies for the Windows/DirectX platform.
Fahrenheit is aimed at supporting applications which rely on interactive graphics, imaging and video.

 OpenGL Does Windows
API’s are what make our lives easier, they make it possible for only a page of code to retrieve a file over the Internet, to easily create standard Windows dialogs and OLE enabled applications, get data from any number of SQL databases, etc. Standard API’s are good.
There are "standard" API’s and tool languages for a variety of development tasks, SQL for database manipulation, Win32 for Windows development, Java and HTML for Internet and Web development, etc. A similar API exists for programs that have the need for functionality that includes 3D graphics.
SGI would provide a solid and portable 3D graphics API that would protect developers investments in software, allow content to be deployed on lower end machines, and allow applications to scale upwards in performance by upgrading hardware.

 Gamasutra - Features - "Fahrenheit: No Spontaneous Combustion Here!" [04.03.98]
Fahrenheit is made up of three pieces: a Scene Graph API, a Large Model Visualization Extension package, and a Low-Level API.
The low-level API is, as I see it, Microsoft's way of gracefully admitting that it's tired of fighting the API wars, that Direct3D isn't the best model for 3D graphics, but then again, neither is OpenGL.
Fahrenheit is intended to replace Direct3D, but this time, Microsoft is actually going to ask around, submit questions, and try to do it right.

 Units: D
In the U.S., the unmodified unit "degree" generally means the degree Fahrenheit; in other countries, it means the degree Celsius.
For highways in the U.S., the angle of curvature is the angle (measured at the center of the circle) spanned by an arc 100 ft long.
Fahrenheit set 0° at the coldest temperature he could conveniently achieve using an ice and salt mixture, and it is said he intended to set 96° as the temperature of the human body.

 Graphics Accelerators
Graphics accelerators are coprocessors that reside in your computer that assist in drawing graphics.
One of the bottlenecks of the earlier graphics accelerators was that the queue would often be too small (typically 16 entries, as is the case of the original ATI Mach 64) to give the host and the graphics accelerator sufficient opportunity for parallelism.
The common implementation of nearly all graphics accelerators when there is a requirement to read or write from the host to graphics memory is to wait until all pending graphics operations are done and the command queue has been emptied first.

 Silicon Graphics - Onyx2 : Developers
APIs were built on OpenGL®;, the industry standard for graphics application development, pioneered by Silicon Graphics.
Its APIs package OpenGL algorithms as higher-level calls, which are employed by programmers to shorten development time and reduce the lines of code to maintain.
Our new volume-imaging API is a library of C++ classes that facilitate visualization of voxel-based data sets common in geoscience, medical, and scientific and engineering applications such as computation fluid dynamics and finite element analysis, as well as those implementing physics-based models for special effects such as smoke, fog, and liquid.

 Microsoft and 3D Graphics
For example, a 3D graphics API might include functions that draw objects, simulate the effects of lights, and determine which objects are visible from a given point of view.
The design of a 3D graphics API determines what can be drawn, how quickly it can be drawn, and how easy it is for a software developer to achieve a desired effect.
For example, the functions of a 3D graphics API might be implemented differently on the video card in a Compaq PC than they would be implemented on another video card in a Dell PC.

 Sun Microsystems-Reality Check
The low-level API does not present anything new, especially since industry trends are moving towards a higher level programming model using scene-graph architecture.
However, Fahrenheit's second level scene graph API carries too much baggage as it will be layered on top of not only OpenGL®; but also Direct3D®; and the yet-to-be-defined Fahrenheit low-level API.
In addition, the Fahrenheit API is a 3D graphics-only solution, not geared for the media-rich applications of tomorrow.

 MS quietly dumps Windows OpenGL support | The Register
Fahrenheit, the joint Microsoft-SGI project "to define the future of graphics" has crashed in ruins, with Microsoft to all intents and purposes pulling its support for OpenGL and throwing its weight behind Direct3D.
One suggests that drivers for a particularly graphics card were pulled because of source code issues, while another says that "we are not supporting OGL until Direct3D is 100 per cent." Which of course suggests that Microsoft support for OpenGL would crack on ahead once Win2k went gold.
This is a spectacular turnaround from the initial Fahrenheit announcement, and quite a reversal from SGI's position of a year ago, when it trumpeted Fahrenheit's importance alongside the announcement of its NT-based Visual Workstations.

The OpenGL®; API (Application Programming Interface) began as an initiative by SGI to create a single, vendor-independent API for the development of 2D and 3D graphics applications.
SGI saw the lack of a standard graphics API as an inhibitor to the growth of the 3D marketplace and decided to lead an industry group in creating such a standard.

But until all the technology of the Fahrenheit project is fully deployed, Microsoft's Maritz acknowledged that developers will continue to have to choose between the two according to their needs.
That low-level API is slated to become the project's primary graphics API for consumer and professional applications on Windows, evolving, the companies say, from a combination of the Direct3D, DirectDraw, and OpenGL technologies.
But the low-level API will also be last in line for the Fahrenheit technology's scheduled roll-out, with current plans calling for introduction of the Windows version in the first half of 2000.
