I am using point plane interpolator to interpolate point properties (from SPH results) on a regular grid; however, I like to have the voids in the domain as zero or null in the dataset. But point plane interpolator interpolate the voids as well. Any suggestion is appreciated. Bests,
Kernel are you using? If you are using the
VoronoiKernel, then that will fill the space with a Voronoi diagram (finding regions closest to each input cell) leaving no voids. However, any of the other kernels will basically splat values with a given
Radius, and that can leave voids.
Thanks for your response. I have tried all the available Kernels; but all of them fill the void. Not sure what is wrong.
Have you tried playing with the
Radius parameter? That specifies how big of a volume each point will cover. It defaults to
1, but if you have a small boundary of points, that might mean total coverage, in which case you would have to lower the
Radius to some small fraction of the boundary.
