GLVF: An Unreliable Stream of Images
URL: home.sara.nl/~bram/usoi www.evl.uic.edu/cavern/glvf Contact: Paul Wielinga, SARA Computing and Networking Services, NL, wielinga @ sara.nl Collaborators: SARA Computing and Networking Services, NL: Paul Wielinga, Bram Stolk SARA has developed a light-weight system for visualizing ultra-high-resolution 2D and 3D images. A key design element is the use of UDP, a lossy network protocol, which enables higher transfer rates but with possible resulting visual artifacts. The viewer may tolerate these artifacts moreso than lower throughput, as the artifacts have a short lifespan. At iGrid, this lossy approach is compared to the more robust SAGE system. (See iGrid demo “GLVF: Scalable Adaptive Graphics Environment.”) Visualization scientists from the USA, Canada, Europe and Asia are creating the Global Lambda Visualization Facility (GLVF), an environment to compare network-intensive visualization techniques on a variety of different display systems. |
