Realisieren Sie 3D-Flipbook-Spezialeffekte basierend auf Javascript-HTML5_Javascript-Kenntnissen

Dies ist eine sehr coole HTML5-3D-Animation zum Umblättern von Büchern. Der Effekt ist relativ einfach, um das Umblättern von Seiten zu simulieren . Der Text und die Bilder im Buch werden auch in 3D angezeigt, was sehr cool ist.

Das Obige ist der Beispielcode für eine HTML5-3D-Animation zum Umblättern von Büchern. Ich hoffe, dass er für alle hilfreich sein wird, um die Javascript-Programmierung zu erlernen.
