# init(capRadius:height:)

Creates a capsule geometry with the specified radius and height.

## Declaration

```swift
convenience init(capRadius: CGFloat, height: CGFloat)
```

## Parameters

- `capRadius`: The radius both of the capsule’s cylindrical body and of its hemispherical ends.
- `height`: The height of the capsule along the y-axis of its local coordinate space.

## Return Value

Return Value A new capsule geometry.

## Discussion

Discussion The capsule is centered in its local coordinate system. For example, if you create a capsule whose cap radius is 5.0 and height is 20.0, it extends from -10.0 to 10.0 in the y-axis, and the circular cross section at the center of its body extends from -5.0 to 5.0 along the x- and z-axes.
