Improvement of Scalability in Sharing Visualization Contents for Heterogeneous Display Environments

An e-Science infrastructure for efficient discussion between researchers at remote sites is required. A Tiled Display Wall (TDW) can display visualization contents on a large, high-resolution display constructed from multiple monitors arranged in a matrix. To realize this infrastructure, visualization contents need to be shared between multiple TDWs at remote sites. Visualcasting is a technique that shares visualization contents between multiple TDWs which have heterogeneous display environments. However, Visualcasting has a scalability issue with the number of TDWs. To improve this issue, we propose a dynamic rearrangement mechanism for Visualcasting. In the evaluation, our proposed mechanism is shown to improve scalability.
