This paper presents a visualization system for tiled display wall (TDW) environments and user interface to control objects on TDW by using multi-touch devices. This system communicates messages between a master node and renderer nodes by using TCP/IP protocol for control of objects and frame synchronization. Renderer nodes receive messages from a master node at each frame, apply messages, and then render images of each frustum. It also enables multi-touch control by creating a thread for communication with multi-touch device on the master node. In this paper, visualization results of a volume rendering technique called stochastic projected tetrahedra are shown on TDW as an application.
