These resources are bundled into a unified platform using OptIPuter-developed technologies, including dynamic lambda allocation, advanced transport protocols, the Distributed Virtual Computer (DVC) middleware, and a multi-resolution visualization system running over the Scalable Adaptive Graphics Environment (SAGE). With these layered technologies, runs a multi-scale correlated microscopy experiment where a biologist images a sample and progressively magnifies it, zooming from an entire system, such as a rat cerebellum, to an individual spiny dendrite. Using both the 100Megapixel LambdaVision display and the auto-stereo Personal Varrier, scientists can effectively and simultaneously view every step of a multi-scale microscopy correlation process, viewing large 2D scenes and 3D subsections of the scene while comparing them to dozens of possible contexts and matching these to live video output of an electron microscope. |
