WebGL (Web Graphics Library) is a JavaScript API for rendering interactive 2D and 3D graphics within web browsers without the need for plugins. In platforms like Arcane Mirage, WebGL enables developers to deploy Unreal Engine content, simulations, and virtual environments directly on web pages, offering users immersive experiences with real-time rendering, interactivity, and high-quality graphics. WebGL leverages GPU acceleration and hardware rendering capabilities of modern web browsers to deliver responsive performance and visual fidelity, supporting applications such as virtual tours, product configurators, educational simulations, and interactive media. By utilizing WebGL with Unreal Engine, developers can create cross-platform experiences accessible via web browsers, enhancing engagement, accessibility, and user experience for online audiences.
