In this paper, we show that histograms represent spatial function distributions with a nearest neighbour interpolation. We confirm that this results in systematic underrepresentation of transitional features of the data, and provide new insight why this occurs. We further show that isosurface statistics, which use higher quality interpolation, give better representations of the function distribution. We also use our experimentally collected isosurface statistics to resolve some questions as to the formal complexity of isosurfaces.
在本文中，我们表明直方图通过最近邻插值来表示空间函数分布。我们证实这会导致数据过渡特征的系统性表示不足，并对其发生原因提供了新的见解。我们进一步表明，使用更高质量插值的等值面统计能更好地表示函数分布。我们还利用实验收集的等值面统计数据来解决一些关于等值面形式复杂性的问题。
