Surface plot or polyline plot

[Kenichiro-Yoshimi (Kyoshimi)]

Hello,

One way to offset the boundary edge is to calculate the signed distance from the boundary and then extract the lines at the offset distance specified by the Contour filter.

For details on how to calculate the signed distance using the Programmable filter, see below.

Compute the signed distance field from a polygonal mesh

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 …
