### Creating a viewport

[`init()`](/documentation/Metal/MTLViewport/init())

Returns a new viewport.

[`init(originX:originY:width:height:znear:zfar:)`](/documentation/Metal/MTLViewport/init(originX:originY:width:height:znear:zfar:))

Returns a new viewport of a specified size at a specified origin.

### Specifying viewport boundaries

[`originX`](/documentation/Metal/MTLViewport/originX)

The x coordinate of the upper-left corner of the viewport.

[`originY`](/documentation/Metal/MTLViewport/originY)

The y coordinate of the upper-left corner of the viewport.

[`width`](/documentation/Metal/MTLViewport/width)

The width of the viewport, in pixels.

[`height`](/documentation/Metal/MTLViewport/height)

The height of the viewport, in pixels.

[`znear`](/documentation/Metal/MTLViewport/znear)

The z coordinate of the near clipping plane of the viewport.

[`zfar`](/documentation/Metal/MTLViewport/zfar)

The z coordinate of the far clipping plane of the viewport.
