我们处理分析和可视化大型数据集的问题。为此，我们考虑基于场域分解为四面体单元的多分辨率表示。我们比较了两种类型的多分辨率表示，它们在细化初始粗网格所应用的规则上有所不同：一种基于四面体二分，一种基于顶点分割。这两种表示可以被视为常见多分辨率模型的实例，我们将其称为多分辨率网格。简要描述了这两种表示的编码数据结构。提出了结构化体数据集的实验比较。
We deal with the problem of analyzing and visualizing large-size volume data sets. To this aim, we consider multiresolution representations based on a decomposition of the field domain into tetrahedral cells. We compare two types of multiresolution representations that differ on the rule applied to refine an initial coarse mesh: one is based on tetrahedron bisection, and one based on vertex split. The two representations can be viewed as instances of a common multiresolution model, that we call a multiresolution mesh. Encoding data structures for the two representations are briefly described. An experimental comparison on structured volume data sets is presented.
