DiSTI’s GL Studio 4.0 supports integration of 2D and 3D Interactive HMI Content into any

Opens Source or COTS OpenGL Scene Graph

Orlando, FL, May 11, 2009 – The DiSTI Corporation, a global leader in Human Machine Interface (HMI) development, today announced the continued extensive support for numerous OpenGL based scene graphs and visualization toolkits with GL Studio 4.0. The toolkit’s open architecture has made GL Studio an industry standard for HMI development enabling straightforward integration into a wide range of application types. The integration trend continues the exciting new visualization solution VR-Vantage developed by VT MÄK.

For nearly a decade, GL Studio has supported the integration of 2D and 3D Cockpits, Symbology and HUDs into third party scene graph solutions. The result is an extensive list of 3D world visualization environments that can benefit from GL Studio developed interface content. Prime contractors have the freedom to select from a variety of these environments knowing that they will be able to integrate high performance high fidelity GL Studio displays. The following is a partial list of 3D visual environments whose scenes have been augmented with GL Studio content:

• Open Scene Graph

• Delta 3D

• V-Tree

• VR-Vantage

• EPX

• Vega Prime

• MÄK Stealth

• pC-NOVA

• NASA World Wind

“Ease of use and open product integration are critical reasons why GL Studio is selected by the global market,” says Darren Humphrey, Chief Technology Officer for DiSTI. “The Training and Simulation market has historically been forced to work with proprietary HMI solutions until the release of GL Studio. We changed the paradigm of the industry with the release of such an open architecture toolkit for the development of cockpits, HUDs, symbology and instrumentation.”
