Hi, I’m new working with some weather data which are only grid points. I found it incompatible with many filters I’m interested in. So I want to use Delaunay3D to convert it into mesh. But Delaunay3D seems to be computational expensive and easily get stuck. Is there certain settings help with the situation, because those points are structured grid.

Welcome to the forum Karl !

A structured grid puts indeed extra stress to the Delaunay filter due to the many co-linear & co-planar points. To create a structured grid from a set of points you may use the `Table to Structured Grid` filter.

For example:

Here is also the corresponding dataset: [points.csv](https://discourse.paraview.org/uploads/short-url/5fmjWuQJOzK3LvxlJy6z6KYJ6cR.csv) (1021 Bytes)

Notice that x coordinate is growing the fastest, then y and then z .
