使用Delanuay 2D过滤器时，Paraview / ParaVis崩溃

Question

我需要使用.CSV文件中的数据在ParaView中创建等高线图（下面显示了CSV文件的内容）。

1. 我打开了.CSV文件。
2. 我使用Apply Filters＆gt;将表格转换为点数。按字母顺序＆gt;表到点。它正确地显示了这些要点。

然而，当我尝试使用Apply Filters＆gt;制作曲面时按字母顺序＆gt; Delaunay 2D，Paraview在没有任何警告或错误消息的情况下崩溃。

感谢您的帮助。

Answer 1

我能够通过围绕x轴将点转换90度，然后应用Delaunay2D滤镜来使数据工作。为此，请按照您的方式加载点，将“表格”应用于“点”过滤器，然后将“过渡”设置的第一个文本框应用到“变换”过滤器为90.最后，应用Delaunay2D过滤器。它应该不会崩溃。

如果要将点恢复到原始坐标空间，请将Delaunay2D滤镜的结果绕x轴转换-90度。

崩溃的可能原因是默认设置是将点投影到XY平面。当您对数据执行此操作时，投影点是共线的，因此Delaunay三角测量不起作用。我没有用Best-Fitting Plane设置下注更好的结果。
