[Click to download larger version] Create Graphic Realism Using Industry-Standard IRIS Graphics Library

The driving force behind the IRIS VME Series Elan & XS Graphics Subsystems is a sophisticated set of programming routines called the IRIS Graphics library (GE). Programmers can access more than 450 GL functions to build realistic, interactive 3D images. Features include:

Put Thousands of 3D Graphics Application Packages To Work With Your Product

Because all IRIS VME Series products are 100% binary compatible with the full line of SGI RISC workstations, you can choose from among thousands of exciting 3D application packages from hundreds of vendors. These include:

Embedded Workstation Graphics Options

The IRIS VME Series Elan & XS Graphics Subsystems bring Silicon Graphics' highest performance desktop graphics to VME format systems. Packaged in industry standard 6U VME format, the Elan-V, XS-V and XS24-V graphics are easily integrated into your company's products. These graphics systems allow you to add interactive visual realism to your application, this enables creating and manipulating realistic, full-color, 3D images in real time. Because its 100% binary compatible with all SGI's workstations, Elan-V & XS-V and XS24-V graphics provide a common environment for your development and target systems.

Typical Applications

Medical Imaging: Integrated into MRI or ultrasound scanning equipment, enables medical personnel to reconstruct and manipulate body images in real time.

Control Room Displays: Compact rack-mountable system provides high-resolution display of aircraft test data, radar tracking, or industrial controls.

Aircraft & Vehicle Simulators: Elan-V's advanced 3D graphics, can display dynamic air & ground views with other vehicles, scenery & heads up display data.
