导入Excel数据以进行Isovolume渲染Paraview [英] Importing Excel Data for Isovolume Rendering Paraview

问题描述

我试图基于 xyz 可视化热强度数据（0到1）。我在excel文件和csv文件中都有数据。在csv中，格式如下：

I am trying to visualize heat intensity data(0 to 1)based on xyz. I have the data in a excel file and also in a csv file. In csv, the format is as follows:

x, y, z, scalar
0, 1, 1, 0.489324
1, 1, 1, 0.899
.
.
.

轴上的每个单位代表一个体素。每个轴上总共有12个体素。我想想像一下这件事-> https://www.youtube.com/watch?v = UMnIwdQhZE4 。如何将Excel数据或csv导入paraview？有没有一种方法可以将粘贴值从Excel工作表复制到3D数组中？

Each unit on an axis represents one voxel. There are totally 12 voxels along each axis. I would like visualize something close to this -> https://www.youtube.com/watch?v=UMnIwdQhZE4. How do i import either an excel data or csv into paraview? Is there a way to copy paste values from excel sheet into a 3d array?

推荐答案

Paraview可以轻松打开csv文件，从而创建表源。加载数据后，您可以使用

Paraview can easily open csv files, creating a table source. Once you load your data, you can use the

1. TableToPoints：我发现这是最简单的选项，您只需选择代表x的列即可，y，z。 outout是一个polygonall网格
   或


2. TableToStructuredGrid：除了选择列之外，您还必须编写范围-在您的情况下，我认为0-11 0-11 0- 11。我对此没有太多经验，但是我想您也必须注意数据是否为x最快的。在这种情况下，输出为结构化网格


3. 如果您必须执行更复杂的操作，则可以使用可编程过滤器并更改输出格式。有关示例，请参见paraview指南。对于合适的格式，这是一个很好的答案 https://stackoverflow.com/a/7667417/1136458

1. TableToPoints: I find it the easiest option, you just have to select which column represent x,y,z. The outout is a polygonall mesh or
2. TableToStructuredGrid: besides choosing the columns, you also have to write the extent - in your case I think 0-11 0-11 0-11 . I don't have much experience with this, but I think you also have to be careful if your data is x-fastest or not. The output in this case is a structuredGrid
3. If you have to do something more complicated, you can use the programmable filter and change the output format. For examples see the paraview guide. For suitable formats, here is a nice answer https://stackoverflow.com/a/7667417/1136458
