playcanvas/engine

PlayCanvas Engine is an open-source game engine written in JavaScript that lets you build interactive 3D games, apps, and visualizations that run directly in a web browser, no plugin or download required for end users. It is powered by WebGL2 and WebGPU (the browser's built-in graphics systems) and supports WebXR for augmented reality and virtual reality experiences. The engine handles every major piece of a game or interactive experience: 3D and 2D graphics, physics so objects can collide and fall realistically, character and scene animations, keyboard/mouse/touch/gamepad input, spatial sound tied to 3D positions, and asset streaming so large files load progressively instead of making users wait. A standout feature is first-class support for "3D Gaussian Splatting," a newer technique for rendering photorealistic scenes captured from real-world photos. You would use PlayCanvas if you want to ship a game, product configurator, interactive ad, or architectural visualization that runs on any device with a browser, desktop or mobile. Game developers, advertising agencies, and companies like BMW, Disney, Snap, and Zynga are listed as users. Developers write game logic in JavaScript or TypeScript, and a companion browser-based visual editor is also available for those who prefer a drag-and-drop workflow. The package installs via npm, and a project scaffolding command can set up a full starter project in seconds.
