                         and have received substantial interest from the scientific 
                         visualization community. In this paper, we take a point-based 
                         approach to rendering unstructured grids. In particular, we 
                         present a novel method of approximating these irregular elements 
                         with point-based primitives amenable to existing hardware 
                         acceleration techniques. To improve interactivity to large 
                         datasets, we have adapted a level-of-detail strategy. We use a 
                         well-known quantitative metric to analyze the image quality 
                         achieved by the final rendering.",
