Note that it is not particularly dense, and the initial visualization is less than compelling as shown. The figure below shows the initial point cloud which is from the VTK test data repository it’s fairly small in size at only ~175,000 points (SPH_Points.vtu). Each of these three approaches are shown in the next subsections. Finally, plotting along a resampled line supports detailed analysis of data values. Plane resampling, which along with the associated plane widget, enables the user to rapidly slice through the data and show a heat map on the resulting plane.

Resampling onto a volume means that volume rendering and standard 3D visualization techniques such as isocontouring can be used on the resulting volume.

After first reading or creating data with points and associated data attributes (e.g., scalars, vectors, and so on), select Filters->Points Interpolation as illustrated below.ĭepending on the type of point data and interpolation process to use (i.e., either generalized or SPH) and whether you want to resample the point data onto a volume, plane or line, six choices are available as shown.

In this article, we describe how to use ParaView to perform point interpolation, which of course uses VTK under the hood, but provides a simple and powerful integrated application GUI to perform the interpolation. Both general point interpolation and smoothed-particle hydrodynamics SPH methods were addressed. In the first article in this two-part series, we provided background and described the implementation of point interpolation in VTK. The first article describes how to perform point interpolation using VTK.) Introduction It shows how to perform point interpolation using ParaView. (This is the second article in a two part series.
