Bounding Regions

Compute convex hull, alpha shape, or boundaries around points


boundaryBoundary of a set of points in 2-D or 3-D
alphaShapePolygons and polyhedra from points in 2-D and 3-D
convhullConvex hull
convhullnN-D convex hull


Computing the Convex Hull

This topic explains several methods for computing the convex hull using convhull, convhulln, delaunayTriangulation, and alphaShape.

Types of Region Boundaries

This topic explains the differences between several types of boundaries that enclose a set of points.
