Nvidia Corp says that the Fahrenheit graphics application programming interface it is working on with Microsoft Corp will see the light of day as part of the Direct X 8.0 API set. However, Dan Vivoli, Nvidia’s VP of marketing, questions how long it will be before the graphics interface is as robust as Silicon Graphics Inc’s OpenGL standard. Nvidia has previously worked with Microsoft to develop the Direct X 6.0 API set and is now working on DX 7.0. Nvidia is also one of the 10 member strong OpenGL board, one of the few PC graphics chips manufacturers on the panel. The Fahrenheit API is said to combine elements of OpenGL and Direct X.
