Plot a function over a stadium:

Create a 3D stadium extrusion with RegionProduct:

Using a series of stadiums (and a disk), create a stick figure:

Use RotationTransform to make the stick figure's limbs pivot:

Make a spring visualization from a collection of stadiums. Make a function that creates a set of stadiums for the front half of the spring and another for the back half, given that each stadium has a horizontal component of :

Set the top layer of the spring to a lighter gray than the back and make it interactively stretchable using Manipulate:

Disk is the limit of StadiumShape as p₁ approaches p₂:

The 3D version of StadiumShape is CapsuleShape:

A StadiumShape formed from the RegionUnion of disks and a rectangle:

The area is the sum of the disk and quadrilateral areas:

StadiumShape is all points no more than from a Line:

ImplicitRegion can represent any StadiumShape:
