Show HN: Understanding the Spatial Web Browser Engine
Experience the future of web browsing with JSAR - an open-source spatial web browser engine for 3D, WebXR, and immersive spatial browsing experiences.
Positioned, rotated, and scaled in world / XR reference spaces Layered with true depth ordering (not just z-index compositing) for stereoscopic correctness Interacted with using spatial input sources (gaze, hands, controllers, future: eye tracking, anchors) Composed alongside native 3D assets ( GLTF models, environment maps) in one unified frame loop Through comprehensive WebXR integration, automatic spatial audio positioning, and intelligent input source abstraction, JSAR enables developers to create immersive experiences using the same HTML, CSS, and JavaScript skills they already possess. JSAR's embedding model as a library within existing 3D engines like Unity, combined with its aggressive batching optimizations and cross-platform support (macOS/Android with OpenGL/GLES3), positions it as a practical solution for both XR applications and desktop innovation.
