| 16 | \brief Defines a pill-like shape. |
|---|
| 17 | |
|---|
| 18 | This type defines a capsule shape. This is a cylinder with a hemisphere at each end. |
|---|
| 19 | The origin is at the center of the capsule. The capsule is specified by \l diameter, which |
|---|
| 20 | determines the diameter of the cylinder and the hemispheres; and \l height, which |
|---|
| 21 | determines the height of the cylinder. |
|---|
| 22 | |
|---|
| 23 | \note When using scaling transformations with this shape, the x component will be used to scale the height and |
|---|
| 24 | the y component will be used to scale the diameter. The cylinder will always be perfectly circular even if the |
|---|
| 25 | scaling transformation is non-uniform. |
