Paraview/ParaVis 使用 Delanuay 2D 滤镜时崩溃
Paraview/ParaVis crashes when I use Delanuay 2D filter
我需要使用 .CSV 文件中的数据在 ParaView 中绘制等高线图（下面显示了 CSV 文件的内容）。
- 我打开了 .CSV 文件。
- 我使用“应用滤镜”>“字母顺序”>“Table 到点”将 table 转换为点。它正确显示了点数。
但是，当我尝试使用“应用滤镜”>“字母顺序”>“Delaunay 2D”制作表面时，Paraview 崩溃，没有任何警告或错误消息。

通过将点绕 x 轴旋转 90 度，然后应用 Delaunay2D 过滤器，我能够让您的数据正常工作。为此，请像您一样加载点，将 Table 应用到点过滤器，然后应用变换过滤器并将 "Rotate" 设置的第一个文本框设置为 90。最后，应用 Delaunay2D 过滤器。它应该可以正常工作而不会崩溃。
如果要将点恢复到原始坐标 space，请将 Delaunay2D 过滤器的结果绕 x 轴变换 -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 三角剖分不起作用。我没有打赌最佳拟合平面设置会有更好的结果。
我需要使用 .CSV 文件中的数据在 ParaView 中绘制等高线图（下面显示了 CSV 文件的内容）。
- 我打开了 .CSV 文件。
- 我使用“应用滤镜”>“字母顺序”>“Table 到点”将 table 转换为点。它正确显示了点数。
但是，当我尝试使用“应用滤镜”>“字母顺序”>“Delaunay 2D”制作表面时，Paraview 崩溃，没有任何警告或错误消息。

通过将点绕 x 轴旋转 90 度，然后应用 Delaunay2D 过滤器，我能够让您的数据正常工作。为此，请像您一样加载点，将 Table 应用到点过滤器，然后应用变换过滤器并将 "Rotate" 设置的第一个文本框设置为 90。最后，应用 Delaunay2D 过滤器。它应该可以正常工作而不会崩溃。
如果要将点恢复到原始坐标 space，请将 Delaunay2D 过滤器的结果绕 x 轴变换 -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 三角剖分不起作用。我没有打赌最佳拟合平面设置会有更好的结果。
