Appian Graphics

Appian Graphics was a supplier of multi-monitor graphics accelerators founded in 1994.

History
The company was best known for its Jeronimo and Gemini product lines, and for the HydraVision display management software. The main competitor for Appian on the multi-monitor solutions market was STB Systems.

The company was acquired in July 2001 by Colorgraphic Communications, Inc., which ceased business in 2007 or 2008.

Appian Graphics originally developed HydraVision in the late 1990s for their multi-head display solutions. ATI Technologies acquired HydraVision in July 2001 along with Appian's HydraVision team to join its then-new dual-head Radeon 7500 and 8500 series.

Appian Rotate was developed in 1998 for hardware accelerated portrait display, it allowed off the shelf graphics components that supported 3D texture mapping for rotating the offscreen desktop screen correctly onto the display out buffer. It has become the default standard in the industry for portrait mode and is still used by display drivers to support portrait display.
