Applications  (6)

Visualize the Platonic solids using CapsuleShape for the edges:

Use CapsuleShape to render edges in a GraphPlot3D:

Use CapsuleShape to render edges in 3D for Graph objects:

Embed the graph in 3D and use CapsuleShape:

Use CapsuleShape to render edges in 3D BoundaryMeshRegion and MeshRegion objects:

Using a series of capsules (and a ball), you can create a stick figure:

Furthermore, you can use RotationTransform to make the stick figure's limbs pivot:

CO2 cartridges have many applications, ranging from sports to soda-making to life jackets. A 12g CO2 cartridge is about 18.6 mm in diameter and 82.5 mm long, with a neck about 12 mm long and 7.3 mm in diameter:

It can be approximated as a capsule and a cylinder:

Knowing that the ideal gas law states , where is the universal gas constant, find the volume of the gas within the cartridge at standard temperature and pressure (273.15 K and 1 bar):

Find the ratio of the normal to compressed volume:

Properties & Relations  (6)

The 2D version of CapsuleShape is StadiumShape:

Ball is the limit of CapsuleShape as p1 approaches p2:

A CapsuleShape formed from the RegionUnion of balls and a cylinder:

The volume is the sum of ball and cylinder volumes:

CapsuleShape is all points at most from a Line:

ImplicitRegion can represent any CapsuleShape:

A rounded Tube looks like a CapsuleShape:
