VRCO Announces Latest CAVELib™ Release Now Supports DVG Graphical Computers from ORAD Orad’s New COTS-Based Visualization Clusters Can Now Access CAVELib’s Powerful Functionality For Highly Scalable PC Performance Viriginia Beach, VA - July 27, 2003 - VRCO Inc., an internationally recognized leader in advanced data visualization solutions, is proud to announce the latest release of CAVELib supports the Orad DVG system. CAVELib, a powerful application programmer interface (API) originally developed for the support of multi-wall CAVE® systems, demonstrates its extensive flexibility once again by supporting this latest development in advanced computer technology. CAVELib, with its maturing support for PC clusters, supports Orad’s DVG system without modifications to the library and without recompilation of cluster based CAVELib applications. VRCO currently offers a visualization cluster solution where each PC is responsible for rendering to a single projector for a multi-projector display system. CAVELib supports this solution by synchronizing the data between each PC, assuring that the images on each display are properly matched. Orad’s DVG solution, which is a departure from the single PC per projector paradigm, allows an application to be split between multiple PC's that will eventually have their video combined for a single projector. The DVG provides visualization scalability by chaining two or more PCs with commercial off-the-shelf (COTS) video cards, and combining their video outputs for a single display projector. The DVG provides several means of chaining the PCs together: time division, sample division, screen division, and image division. Each provides a different mechanism for scalability depending on the application. According to VRCO Chief Technology Officer Matt Szymanski, most CAVELib applications will fall into the realm of sample division or image division. "Sample division provides multi-sample antialiasing, which results in a higher quality image without sacrificing performance," states Szymanski. "Whereas, image division allows each PC to render a fraction of the overall viewport. By having each machine render smaller viewport, applications that are bound by pixel fill rates can increase their frame rates without having to decrease their polygon count." Depending upon what chaining mode the DVG is set up for, CAVELib configuration files will require changing. This is a simple modification though, and does not require editing or recompilation of an application. Part of the ability to execute applications on the DVG without recompilation comes because of the use of Orad's OpenGL® wrapper. This wrapper intercepts certain OpenGL calls from the application and executes the necessary commands to display properly for the type of chaining for which the DVG is configured. "The real beauty of the DVG is in the OpenGL wrapper," continues Szymanski. "With the wrapper, CAVELib customers will not have to modify their applications to take advantage of the DVG. As long as the application is cluster capable, it will simply run on the DVG." The ability to make use of new hardware with little effort is a real boon for CAVELib and the DVG, as well as a testament to the advanced design and flexibility of these products. "CAVELib is an industry standard that benefits from years of R&D and support, and we are impressed by the versatility of this solution that addresses a very large array of needs in immersive environments," states Guillaume Otrage, Vis Sim business development manager for Orad. "The port of this software to the Orad DVG will open large markets for our platform and answer numerous queries we had from end-users. We are very excited about the relationship that we have with VRCO and believe that our joint solution can deliver scalable performance at the best price point and total cost of ownership." ### About Mechdyne Corporation Mechdyne Corporation is the world’s largest company dedicated to consulting and development of immersive, networked and collaborative visualization systems.
