1，先使用create zone --建立rectangular（正交的区域）
2，在使用interpolate--插值到新建的zone区域。

Example - Unorganized Three-Dimensional Volume

To use 3D volume irregular data in field plots, you must interpolate the data onto a regular, IJK-ordered zone. (Tecplot 360 does not have a 3D equivalent for triangulation.) To interpolate your data, perform the following steps:

1. Place your 3D volume irregular data into an I-ordered zone in a data file.

2. Read in your data file and create a 3D scatter plot.

3. From the Data menu, choose Create Zone>Rectangular. (Circular will also work.)

4. In the Create Rectangular Zone dialog, enter the I-, J-, and K-dimensions for the new zone; at a minimum, you should enter 10 for each dimension. The higher the dimensions, the finer the interpolation grid, but the longer the interpolating and plotting time.

5. Enter the minimum and maximum X, Y, and Z values for the new zone. The default values are the minimums and maximums of the current (irregular) dataset.

6. Click [Create] to create the new zone, and [Close] to dismiss the dialog.

7. From theData menu, choose Interpolate>Kriging. (Linear or Inverse distance Interpolation also work.)

8. In the Kriging dialog, choose the irregular data zone as the source zone, and the newly created IJK-ordered zone as the destination zone. Set any other kriging parameters as desired (see Kriging for details).

9. Select the[Compute] button to perform the kriging.

Once the interpolation is complete, you can plot the new IJK-ordered zone as any other 3D volume zone. You may plot iso-surfaces, volume streamtraces, and so forth. At this point, you may want to deactivate or delete the original irregular zone so as not to conflict with plots of the new zone.

Figure 2-3 shows an example of irregular data interpolated into an IJK-ordered zone, with iso-surfaces plotted on the resultant zone.
