Houdini 20.0 Nodes Geometry nodes

Shrinkwrap geometry node

Takes the convex hull of input geometry and moves its polygons inwards along their normals.

Since 12.0

The Shrinkwrap operation computes the convex hull of the input geometry using the same method as Tetrahedralize, and translates the resultant polygonal primitives inwards along their normals. Unlike the Peak SOP, which takes the point and moves it according to the average of the neighboring polygons, Shrinkwrap moves the polygons and recomputes their intersections, possibly creating new and removing old points, but maintaining polygon normal directions. Polygons with more than three edges are divided into triangles with the same normals as the original polygon.

Parameters

Distance

The translation distance inwards.

Clip Tolerance

The error tolerance for computing the new point positions.

Consolidate Tolerance

The error tolerance for fusing points together. This is equivalent to using consolidate points in the Facet SOP.
