Camera3D

Conformances

• protocol CustomStringConvertible

  A type with a customized textual representation.

• protocol Equatable

  A type that can be compared for value equality.

• protocol Hashable

  A type that can be hashed into a Hasher to produce an integer hash value.

• protocol Identifiable<ID>

  A class of types whose instances hold the value of an entity with stable identity.

• protocol VariantRepresentable

  Types that conform to VariantRepresentable can be stored directly in Variant with no conversion. These include all of the Variant types from Godot (for example GString, Rect, Plane), Godot objects (those that subclass SwiftGodot.Object) as well as the built-in Swift types UInt8, Int64 and Double.

• protocol VariantStorable

  Types that conform to VariantStorable can be stored in a Variant and can be extracted back out of a Variant.

Types

• enum DopplerTracking
• enum KeepAspect
• enum ProjectionType

Type members

• class var godotClassName: StringName

Instance members

• var attributes: CameraAttributes?

  The CameraAttributes to use for this camera.

• var cullMask: UInt32

  The culling mask that describes which layers are rendered by this camera. By default, all 20 user-visible layers are rendered.

• var current: Bool

  If true, the ancestor Viewport is currently using this camera.

• var dopplerTracking: Camera3D.DopplerTracking

  If not .disabled, this camera will simulate the Doppler effect for objects changed in particular _process methods. See DopplerTracking for possible values.

• var environment: Environment?

  The Environment to use for this camera.

• var far: Double

  The distance to the far culling boundary for this camera relative to its local Z axis. Higher values allow the camera to see further away, while decreasing far can improve performance if it results in objects being partially or fully culled.

• var fov: Double

  The camera’s field of view angle (in degrees). Only applicable in perspective mode. Since keepAspect locks one axis, fov sets the other axis’ field of view angle.

• var frustumOffset: Vector2

  The camera’s frustum offset. This can be changed from the default to create “tilted frustum” effects such as Y-shearing.

• var hOffset: Double

  The horizontal (X) offset of the camera viewport.

• var keepAspect: Camera3D.KeepAspect

  The axis to lock during fov/size adjustments. Can be either .keepWidth or .keepHeight.

• var near: Double

  The distance to the near culling boundary for this camera relative to its local Z axis. Lower values allow the camera to see objects more up close to its origin, at the cost of lower precision across the entire range. Values lower than the default can lead to increased Z-fighting.

• var projection: Camera3D.ProjectionType

  The camera’s projection mode. In .projectionPerspective mode, objects’ Z distance from the camera’s local space scales their perceived size.

• var size: Double

  The camera’s size in meters measured as the diameter of the width or height, depending on keepAspect. Only applicable in orthogonal and frustum modes.

• var vOffset: Double

  The vertical (Y) offset of the camera viewport.

• func clearCurrent(enableNext: Bool)

  If this is the current camera, remove it from being current. If enableNext is true, request to make the next camera current, if any.

• func getCameraProjection() -> Projection

  Returns the projection matrix that this camera uses to render to its associated viewport. The camera must be part of the scene tree to function.

• func getCameraRid() -> RID

  Returns the camera’s RID from the RenderingServer.

• func getCameraTransform() -> Transform3D

  Returns the transform of the camera plus the vertical (vOffset) and horizontal (hOffset) offsets; and any other adjustments made to the position and orientation of the camera by subclassed cameras such as XRCamera3D.

• func getCullMaskValue(layerNumber: Int32) -> Bool

  Returns whether or not the specified layer of the cullMask is enabled, given a layerNumber between 1 and 20.

• func getFrustum() -> VariantCollection<Plane>

  Returns the camera’s frustum planes in world space units as an array of Planes in the following order: near, far, left, top, right, bottom. Not to be confused with frustumOffset.

• func getPyramidShapeRid() -> RID

  Returns the RID of a pyramid shape encompassing the camera’s view frustum, ignoring the camera’s near plane. The tip of the pyramid represents the position of the camera.

• func isPositionBehind(worldPoint: Vector3) -> Bool

  Returns true if the given position is behind the camera (the blue part of the linked diagram). See this diagram for an overview of position query methods.

• func isPositionInFrustum(worldPoint: Vector3) -> Bool

  Returns true if the given position is inside the camera’s frustum (the green part of the linked diagram). See this diagram for an overview of position query methods.

• func makeCurrent()

  Makes this camera the current camera for the Viewport (see class description). If the camera node is outside the scene tree, it will attempt to become current once it’s added.

• func projectLocalRayNormal(screenPoint: Vector2) -> Vector3

  Returns a normal vector from the screen point location directed along the camera. Orthogonal cameras are normalized. Perspective cameras account for perspective, screen width/height, etc.

• func projectPosition(screenPoint: Vector2, zDepth: Double) -> Vector3

  Returns the 3D point in world space that maps to the given 2D coordinate in the Viewport rectangle on a plane that is the given zDepth distance into the scene away from the camera.

• func projectRayNormal(screenPoint: Vector2) -> Vector3

  Returns a normal vector in world space, that is the result of projecting a point on the Viewport rectangle by the inverse camera projection. This is useful for casting rays in the form of (origin, normal) for object intersection or picking.

• func projectRayOrigin(screenPoint: Vector2) -> Vector3

  Returns a 3D position in world space, that is the result of projecting a point on the Viewport rectangle by the inverse camera projection. This is useful for casting rays in the form of (origin, normal) for object intersection or picking.

• func setCullMaskValue(layerNumber: Int32, value: Bool)

  Based on value, enables or disables the specified layer in the cullMask, given a layerNumber between 1 and 20.

• func setFrustum(size: Double, offset: Vector2, zNear: Double, zFar: Double)

  Sets the camera projection to frustum mode (see .projectionFrustum), by specifying a size, an offset, and the zNear and zFar clip planes in world space units. See also frustumOffset.

• func setOrthogonal(size: Double, zNear: Double, zFar: Double)

  Sets the camera projection to orthogonal mode (see .projectionOrthogonal), by specifying a size, and the zNear and zFar clip planes in world space units. (As a hint, 2D games often use this projection, with values specified in pixels.)

• func setPerspective(fov: Double, zNear: Double, zFar: Double)

  Sets the camera projection to perspective mode (see .projectionPerspective), by specifying a fov (field of view) angle in degrees, and the zNear and zFar clip planes in world space units.

• func unprojectPosition(worldPoint: Vector3) -> Vector2

  Returns the 2D coordinate in the Viewport rectangle that maps to the given 3D point in world space.

Subclasses
