BUILT-IN SYMBOL

ShellRegion[reg]

gives a solid shell of a 3D region reg.

ShellRegion[reg,t]

gives a solid shell of reg with minimal thickness t.

Examplesopen allclose all Basic Examples  (2)

Find the shell of a ball:

Find the shell of a mesh region:

Specify a thickness:

Scope  (16) Basic Uses  (3)

ShellRegion works on solid regions:

Closed surfaces:

Specify a thickness for a shell:

Formula Regions  (2)

Find the shell of an ImplicitRegion:

Visualize the shell:

A Boolean combination of inequalities:

Visualize the shell:

Applications  (5)

Hollow out a 3D model:

A torus:

A molecule:

Find a shell with roughly one quarter the original volume:

Sample points in the region to create a distribution of distances to the boundary:

Find the distance where one quarter of the sampled points are closer to the boundary:

The resulting shell:

Compare the volumes:

Use ShellRegion to save material when printing a 3D object:

The shell requires less material:

Properties & Relations  (3)

ShellRegion preserves the outer surface of an object:

Extract the outer surface:

Compare properties:

Typically, the thickness of the shell is roughly uniform:

Extract the inner and outer surfaces:

Compute distances to the outer surface with RegionDistance:

The shell of Ball is SphericalShell:

Use ShellRegion to compute the shell of other regions:

Possible Issues  (2)

The thickness of a shell may not be uniform:

Different representations of a region can give different shells:
