NodeCamera class Scene graph

A Camera whose view comes from a node's world transform: the +Z axis is the look direction, +Y is up, and the translation is the eye. This is the inverse of the eye/target/up convention PerspectiveCamera builds, so a node placed at inverse(camera.getViewMatrix()) yields the same view.

The transform is read at render time, so the camera tracks the node live. Usually obtained from CameraComponent.toCamera.

Inheritance

Constructors

NodeCamera(Node node, CameraProjection projection)
Creates a camera that tracks node with the given projection.

Properties

forward → Vector3
The world-space direction the camera looks along (unit length).
no setteroverride
hashCode → int
The hash code for this object.
no setterinherited
node → Node
The node whose world transform drives the view.
final
position → Vector3
The world-space position of the camera (the eye point). Used by materials for view-dependent shading (e.g. specular reflections).
no setteroverride
projection → CameraProjection
The lens projection paired with this camera's view.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
up → Vector3
The world-space up direction used to orient the camera around forward.
no setteroverride

Methods

getFrustum(Size dimensions) → Frustum
Returns the view frustum (six normalized clip planes) for a render target of the given dimensions.
inherited
getViewMatrix() → Matrix4
Returns the world-to-view transform (the view matrix), independent of the render target size.
override
getViewTransform(Size dimensions) → Matrix4
Returns the combined projection-and-view transform for a render target of the given dimensions.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
screenPointToRay(Offset screenPosition, Size viewSize) → Ray
Maps a position inside a view (logical pixels, origin top-left) to the world-space ray leaving the camera through that point, for picking (Scene.raycast) and pointer input. viewSize is the view's logical size (the constraints SceneView renders into).
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
