SARA has developed a lightweight 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.
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.
