I have a CSV file with comma separated coordinates and a velocity vector of the form: X, Y, Z, Vx, Vy, Vz similar to this post Creating vector field from csv data. I can use the `table to points`

filter with XYZ coordinates, use `merge vector components`

filter to merge Vx, Vy, Vz into velocity vector, and then use `glyph`

filter to visualize the velocity vectors at each point. However, I want to create a 3D contour using the velocity vector and points or a 2D contour using the YZ vectors and points. Is this possible with this data format?

you should be able to use the `Table to Structured Grid`

filter as suggested in the previous thread and apply the contour filter on in.

If not could you share some example data ?

When I apply `Table to Points`

and then the `Contour`

filter with `compute gradients`

checked and contour by `Vz`

, I don’t see any visual appear. I’ll try to see if `Table to Structured Grid`

works with contours, but I haven’t been able to so far. Here is an example of what a section of the data looks like.

Thank you for sharing the data!

Indeed the `Table to Points `

is the right filter for the first step based on your data.

Before you can apply contour you would need to have a mesh connecting the points.

Since the points fit on a plane you can use the `Delaunay2D`

filter using `Best-Fitting Plane`

as projection Plane mode and then apply the contour on the output of it.
