A visualization adapter for SAGE-enabled tiled display wall

Visualization has been taking a role of much importance in both science and business areas. For scientists, visualization is a method to gain the meaning of and insight from scientific data and computational results; for business marketing area, computer visualization is popular as a digital signage technology. Recently, tiled display wall (TDW) has gathered users´ attention and concern as a promising large-scale visualization technique. SAGE (Scalable Adaptive Graphics Environment) is a representative middleware for realizing such a TDW and experimentally used in an inquisitive way at research institutions and universities. However, this SAGE has an undesirable problem that existent X-window based visualization applications are not displayed without source code modification, although it provides a suite of APIs with which developers can write visualization applications displayed on the SAGE-enabled TDW. In this paper, we present an adapter solution that allows users to display X-window application on the SAGE-based TDW without source code modification. In our evaluation, the developed adapter solution incurred a small overhead in displaying an X application onto a SAGE-enabled TDW, in comparison with the case of modifying the source code of it.
