Sort-middle Stream-based Real-time Rendering on Commodity Clusters

Not only do our results indicate that sort-middle is feasible to implement on a cluster, but also that in some cases it has advantages in terms of load-balance and reduced network traffic. This is especially true in cases where dynamic scenes must be rendered in immediate mode or where geometric entities in a scene are unorganized spatially. Additionally, we found that sort-middle is capable of efficiently utilizing nodes that do not support graphics processing units (GPUs) in GPU-limited clusters.
