Hello,

I hope the following link is helpful to compute the signed distance field from STL to points in the Programmable filter.

> Goal Compute the signed distance field from points in a data set to a polygonal mesh. The signed distance field has many applications in computational geometry, and can be used, for instance, to find intersections of objects with a polygonal mesh. Background A signed distance field is a point-associated field that gives the distance from each point in a data set to some location or object. In this case, we’ll compute the signed distance as the nearest point on a polygonal mesh. The sign of the …
