From my own code.

Does your own code manipulate volumic data at any point ? Is it a point based simulation ?

It is point based. For that reason, in the first post, particles are seen in the figure on the right.

Since your data set does not look too big, I would suggest using one of the Delaunay filters to draw triangles or tetrahedra. If your points are on a 2D plane, use the `Delaunay 2D` filter. If your points are in general 3D position, use `Delaunay 3D`.

There are other ways to estimate grids between discrete points, but this will probably be easiest for your data.

I was able to draw streamlines by this method. Thank you very much.
