ResourceRealizer class

Turns a document's resources into live, GPU-backed Geometry and Material objects, memoizing each so a resource shared by many nodes is realized once.

Procedural and payload-backed geometry, parameter materials, and embedded rgba8 textures realize synchronously. External image assets, encoded (PNG/JPEG) image payloads, and fmat materials need decoding or asset loading, so they are resolved by preload (await it before realizing); the synchronous path falls back to a placeholder for them.

Constructors

ResourceRealizer(SceneDocument document, {AssetBundle? bundle})

Creates a realizer over document. bundle (default rootBundle) resolves external image assets and fmat materials during preload.

Properties

bundle → AssetBundle

The asset bundle external assets and fmat materials load from.

final

document → SceneDocument

The document whose resources are realized.

final

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

geometry(LocalId id) → Geometry

The live geometry for resource id, realized and memoized on first use. The result is stamped with its origin so the serializer can recover it.

material(LocalId id) → Material

The live material for resource id, realized and memoized on first use.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

preload() → Future<void>

Resolves the resources that need asynchronous work (external image assets, encoded image payloads, and fmat materials), caching them so the synchronous realize path finds them ready.

texture(LocalId id) → Texture

The live texture for resource id, realized and memoized on first use.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
