Streaming ultra high resolution images to large tiled display at nearly interactive frame rate with vl3

Abstract

Visualization of large-scale simulations running on supercomputers requires ultra-high resolution images to capture important features in the data. In this work, we present a system for streaming ultra-high resolution images from a visualization cluster to a remote tiled display at nearly interactive frame rates. vl3, a modular framework for large scale data visualization and analysis, provides the backbone of our implementation. With this system we are able to stream over the network volume renderings of a 20483 voxel dataset at a resolution of 6144×3072 pixels with a frame rate of approximately 3.3 frames per second.
