That’s right, today we get to officially announce that v5 has landed in the PixiJS master branch and also on npm. This is a huge step as it me
OffscreenCanvas(オフスクリーンキャンバス)はWeb Workers(ウェブワーカー)を使用してWorkerスレッドで描画処理を行える機能です。負荷の高い描画処理をWorkerスレッドに移動することで、メインスレッドの負担が軽くなり、余裕ができます。これによりメインスレッドでスムーズなユーザー操作を実現できるようになり、ユーザー体験の向上が期待できます。本記事ではOffscreenCanvasについて機能と使い方を解説します。 ▲ OffscreenCanvasを使用したデモ。OffscreenCanvasを使用すると、Canvasへの描画負荷が高い場合でもスムーズなユーザー操作とCSSアニメーションの再生を実現できる JavaScriptでマルチスレッドに処理を実行できるWeb Workers OffscreenCanvasの説明の前に、まずはWeb Workersについて
