# Viewpoint

Camera viewpoint parameters in 3D space.

## Declaration

```swift
struct Viewpoint
```

## Overview

Overview This structure represents a camera or observer’s position and viewing direction, with optional availability flags for each component. This allows partial viewpoint information to be represented when only position or direction is known.

## Topics

### Initializers

- [init()](computegraph/viewpoint-swift.struct/init().md)
- [init(position:direction:has_position:has_direction:)](computegraph/viewpoint-swift.struct/init(position:direction:has_position:has_direction:).md)

### Instance Properties

- [direction](computegraph/viewpoint-swift.struct/direction.md)
