Array with object's animation clips.
The sprite's anchor point, and the point around which the Sprite rotates. A value of (0.5, 0.5) corresponds to the midpoint of the sprite. A value of (0, 0) corresponds to the lower left corner of the sprite.
Array with object's children.

When this is set, it checks every frame if the object is in the frustum of the camera before rendering the object.
If set to false the object gets rendered every frame even if it is not in the frustum of the camera.

If set, then the renderer checks every frame if the object and its children need matrix updates. When it isn't, then you have to maintain all matrices in the object and its children yourself.

When this is set, it calculates the matrixWorld in that frame and resets this property to false.

An optional callback that is executed immediately after a 3D object is rendered.
This function is called with the following parameters: renderer, scene, camera, geometry, material, group.
Please notice that this callback is only executed for renderable 3D objects. Meaning 3D objects which
define their visual appearance with geometries and materials like instances of Mesh, Line,
Points or Sprite. Instances of Object3D, Group or Bone are not renderable
and thus this callback is not executed for such objects.
An optional callback that is executed immediately after a 3D object is rendered to a shadow map.
This function is called with the following parameters: renderer, scene, camera, shadowCamera, geometry,
depthMaterial, group.
Please notice that this callback is only executed for renderable 3D objects. Meaning 3D objects which
define their visual appearance with geometries and materials like instances of Mesh, Line,
Points or Sprite. Instances of Object3D, Group or Bone are not renderable
and thus this callback is not executed for such objects.
An optional callback that is executed immediately before a 3D object is rendered.
This function is called with the following parameters: renderer, scene, camera, geometry, material, group.
Please notice that this callback is only executed for renderable 3D objects. Meaning 3D objects which
define their visual appearance with geometries and materials like instances of Mesh, Line,
Points or Sprite. Instances of Object3D, Group or Bone are not renderable

SharedStageBillboard クラスは、単一の共有 Canvas および Texture を使用して描画されるビルボード機能を提供します。 Three.js の Sprite を継承し、共有テクスチャ上の特定の領域を表示します。
概要
SharedStageTexture を使用し、共有テクスチャ上の特定の領域をビルボードとして表示します。
MultiView クラス群との比較
MultiViewPixiBillboard クラスと比較して、SharedStageBillboard は単一の共有CanvasとTextureを使用するため、 テクスチャとマテリアルインスタンスを複数のビルボードで共有可能で、ドローコール数の削減が期待できます。 一方、共有Canvasのサイズに限界があり、多数のビルボードを配置するとテクスチャのマッピングに失敗する可能性があります。 また、部分的な内容更新が多い場合には、共有 Canvas 全体の再描画が必要となり、パフォーマンスが低下する可能性があります。
SharedStageBillboard は、ビルボードの数が比較的固定されており、パフォーマンスのためにドローコール数を削減したい場合に適しています。
ジオメトリに関する注意
一般的なSpriteインスタンスでは、固定値のBufferGeometryを使用しますが、 SharedStageBillboardクラスでは、以下の理由でこの固定値BufferGeometryを使用せず、PlaneGeometryを使用しています。
