Interactive, Internet Delivery of Visualization via Structured, Prerendered Multiresolution Imagery

摘要

One of the fundamental problems in remote visualization--where I/O and data intensive visualization activities take place at a centrally located supercomputer center and resulting imagery is delivered to a remotely located user--is reduced interactivity resulting from the combination of high network latency and relatively low network bandwidth.This research project has produced a novel approach for latency-tolerant delivery of visualization and rendering results where client-side frame rate display performance is independent of source dataset size, image size, visualization technique or rendering complexity. As such, it is asuitable solution for remote visualization image delivery for any visualization or rendering application that can generate image frames in an ordered fashion. This new capability is suitable for use in addressing many of ASCR's remote visualization needs, particularly deployment at open computing facilities to provide remote visualization capabilities to teams of scientific researchers.
