Turns Point Values into a field defined everywhere by interpolating between the samples. Flat or collinear points fall back to the closest sample's value, with a warning.
The Point Values to interpolate: numbers or vectors.
How space between samples is filled. Barycentric blends linearly inside the tetrahedra spanned by the points, a good fit for simulation results; Nearest copies the closest point's value. Outside the points' hull both use the closest point.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
The field read as a Solid whose surface is where the field is zero.
The box the field is evaluated in.
The field with its sign flipped (−f), which swaps inside and outside.
The field divided by its gradient length (f/|∇f|) so it reads close to a true distance; the zero set does not move.
