  text: 'We present a parallel rendering system for PC-Clusters to visualize large
    3D scenes. One single visualization node, equipped with a high-end graphics adapter,
    is supported by a group of backend nodes with weak graphics performance. The objects
    of the scene are distributed among these backend nodes, they serve two purposes:
    First, they provide an out-of-core memory system for the visualization node. Second,
    they assist the visualization node''s rendering by performing visibility calculations
    and only sending visible objects to the visualization node. In order to obtain
    fast rendering with our system, we have to distribute the objects among the backend
    nodes in a way that does not only guarantee an even distribution of the objects,
    but also an even distribution of the visibility calculations and the amount of
    data send to the visualization node. We identify necessary properties of the distribution
    and argue that a random distribution is a good candidate. Further, in order to
    reduce the number of objects sent to the visualization node per frame, we employ
    an approximate hierarchical occlusion culling in each backend node. For this,
    they are equipped, in addition to the objects assigned to them, with simplified
    versions of the other objects of the 3D scene. The visualization node is equipped
    with 512 MiB video memory and supported by 15 backend nodes. This system is able
    to render a approx. 350 million polygons (approx. 8.5 GiB) large aircraft model
    between 20 - 30 fps and thus allows a walkthrough in real-time.'
