The Shrinkwrap SOP computes the convex hull of the input points, and shifts the resulting polygons along their normals to shrink or grow the shape. This algorithm is also used by the Bullet solver to build convex hull collision shapes.
The points to use when computing the convex hull.
After computing the convex hull, each polygon will be shifted inward by this amount. A negative value will expand the convex hull outward.
Preserve Attributes and Groups
Transfers attributes and groups from the input geometry to the convex hull’s points.
Remove Inline Points
Remove points from polygons if they lie on the line connecting the previous and next point. Shrinking by a positive amount may introduce inline points.
