With this paper we focus on complex display environments in which several users view upon numerous types of 3D displays. We present a method for synchronization and shared state management for independent rendering processes. Our approach is based on TCP/IP based virtual shared memory architecture and intelligent clients in order to accomplish state coherent rendering on multiple displays. We describe a series of benchmark tests that we used to identify frame-to-frame incoherency for rendering of animated objects. The results of these tests allow for a quantitative assessment of the underlying distribution model for networked rendering.
