Hello Everyone,

This is a follow up to my previous post [here](https://discourse.paraview.org/t/visualization-of-data-using-paraview/4703)

I have a parameter data `pressure` , obtained from a simulation, for certain xyz coordinates of a geometry (data: first snapshot and geometry displayed in second snapshot shared below).

I don’t have the field values at all points. The values are generated from simulations only at discrete points (x,y,z coordinates displayed in the snapshot below)

Following the instructions given [here](https://discourse.paraview.org/t/visualization-of-data-using-paraview/4703/14), I have used SPH Interpolation by adjusting the `Spatial Step` to interpolate the values of pressure at all points in the geometry.

But these values keep changing when I keep increasing the step size. For instance , I am checking the values for spatial step size: 10, 100, 1000, 1000000. For any value greater than 1000 , the interpolated values of pressure are the same all points as displayed in the above snapshot. I’d like to know what’s the right way to fix this step size.

I would also like to know how to color the 3D geometry using these interpolated values.
