挖掘拓扑结构是获取数据场关键信息的有效途径, Morse-Smale (MS) 复形是二维标量场重要
拓扑结构, 传统方法均采用分片线性模型, 利用离散Morse 理论进行MS 复形分割, 精度较低 …

Visualizing multivariate volume data is useful when the user wants to inspect the
correlational distributions of multiple variables in a spatial field. Existing solutions commonly …

In this paper, we propose a fast and stable evaluation method for the analytic derivatives of
splines generated by the 7-direction quartic box-spline. We can maintain the spline structure …

传统体绘制方法难以清晰地展现体数据的内部结构, 本文提出了基于连续框架的利用数据拓扑
特征增强体绘制的新方法. 该方法首先利用7 方向box 样条拟插值对离散数据进行连续重建 …

Mining topology structure is an effective way of obtaining key information of data fields, and
MorseSmale (MS) complex is an important topology of two dimensional scalar fields. The …

Traditional visualization approaches for volumetric data are not able to reflect clear interior
structures of input data. We present a method to enhance volume rendering by topological …
