Skeleton class

Use an array of bones to create a skeleton that can be used by a SkinnedMesh.

// Create a simple "arm"

final bones = [];

final shoulder = Bone();
final elbow = Bone();
final hand = Bone();

shoulder.add( elbow );
elbow.add( hand );

bones.add( shoulder );
bones.add( elbow );
bones.add( hand );

shoulder.position.y = -5;
elbow.position.y = 0;
hand.position.y = 5;

final armSkeleton = Skeleton( bones );

See the SkinnedMesh page for an example of usage with standard BufferGeometry.

Constructors

Skeleton([List<Bone>? bones, List<Matrix4>? boneInverses])

bones - The array of bones. Default is an empty array.

Properties

boneInverses ↔ List<Matrix4>

getter/setter pair

boneMatrices ↔ Float32List

late, final

bones ↔ List<Bone>

getter/setter pair

boneTexture ↔ DataTexture?

getter/setter pair

boneTextureSize ↔ int

frame ↔ double

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

uuid ↔ String

Methods

calculateInverses() → void

Generates the page:.boneInverses boneInverses array if not provided in the constructor.

clone() → Skeleton

Returns a clone of this Skeleton object.

computeBoneTexture() → Skeleton

Computes an instance of DataTexture in order to pass the bone data more efficiently to the shader. The texture is assigned to boneTexture.

dispose() → void

Frees the GPU-related resources allocated by this instance. Call this method whenever this instance is no longer used in your app.

fromJson(Map<String, dynamic> json, Map<String, Bone?> bones) → Skeleton

getBoneByName(String name) → Bone?

name - String to match to the Bone's .name property.

getValue(String name) → Float32List

init() → void

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

pose() → void

Returns the skeleton to the base pose.

toJson() → Map<String, dynamic>

toString() → String

A string representation of this object.

inherited

update() → void

Updates the boneMatrices and boneTexture after changing the bones. This is called automatically by the WebGLRenderer if the skeleton is used with a SkinnedMesh.

Operators

operator ==(Object other) → bool

The equality operator.
