Camera class abstract Scene graph

A view onto a scene: a world-space eye position and orientation paired with a lens projection, used by Scene.render to map the scene into clip space.

A camera separates its view (where it is and which way it looks, from getViewMatrix) from its projection (the lens, a CameraProjection). PerspectiveCamera is the built-in free camera, positioned by eye/target/up. Attach a CameraComponent to a Node to drive the view from that node's transform instead.

Properties

forward → Vector3
The world-space direction the camera looks along (unit length).
no setter
hashCode → int
The hash code for this object.
no setterinherited
position → Vector3
The world-space position of the camera (the eye point). Used by materials for view-dependent shading (e.g. specular reflections).
no setter
projection → CameraProjection
The lens projection paired with this camera's view.
no setter
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 setter

Methods

getFrustum(Size dimensions) → Frustum
Returns the view frustum (six normalized clip planes) for a render target of the given dimensions.
getViewMatrix() → Matrix4
Returns the world-to-view transform (the view matrix), independent of the render target size.
getViewTransform(Size dimensions) → Matrix4
Returns the combined projection-and-view transform for a render target of the given dimensions.
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).
toString() → String
A string representation of this object.
inherited

Operators

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