ModelThumbnails class final

Pictures of model files for the Assets dock and the palettes, rendered off screen with the 3-D renderer — no engine, no scene — one at a time, and kept until the file changes.

Where there is no GPU (a test, the web) every picture is null and the dock shows the file's icon.

Constructors

ModelThumbnails({required String root, int size = 128, String? cacheFolder, GpuDevice? device})

Thumbnails size pixels square of files under root.

Properties

cacheFolder → String?

Where pictures are kept between sessions (PNG files named after the model and when it changed), or null to keep them in memory only.

final

hashCode → int

The hash code for this object.

no setter, inherited

revision → ValueNotifier<int>

Bumped when a picture is ready; what a view listens to.

final

root → String

The project folder model paths are under.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

size → int

Width and height of each picture, in pixels.

final

Methods

dispose() → void

Lets the pictures go.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

of(String path, {DateTime? modified}) → Future<Image?>

The picture of the model at path as it was at modified: null without a GPU or when the file can't be read as a model.

peek(String path, {DateTime? modified}) → Image?

The picture of the model at path (project-relative) as it was at modified, if it is ready; asking starts it.

renderer() → Future<Renderer3D?>

The renderer the pictures are made with (shadows off), shared with whatever else previews models; null without a GPU.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

frameBounds(Aabb3 box, int width, int height, {Vector3? toward, double yaw = -0.6, double pitch = -0.45}) → RenderView

A view of box, width by height, far enough back to see all of it: from toward (a direction from its middle to the eye), or — when that is null — turned yaw and tipped pitch (radians).

frameModel(ModelData data, int size) → RenderView

A view of data from above and to the front-left, far enough back to see all of it, size pixels square.
