- A Spatial Web Browser interprets and presents web content in 3D space, allowing DOM elements to be positioned, rotated, and scaled in 3D.
- Traditional browsers are optimized for 2D, making retrofitting for 3D spatial semantics challenging, hence the need for a purpose-built Spatial Web Browser Engine like JSAR.
- JSAR's Spatial Web Browser Engine supports standards like HTML5, CSS3, WebGL, and WebXR, with spatialized DOM elements and unified rendering passes.
- Core capabilities include spatialized DOM with 3D properties, unified graphics pipeline for HTML and 3D content, and standards compatibility for existing web knowledge reuse.
- JSAR supports stereo rendering, spatial audio, spatial images, and WebXR input sources, enhancing immersive experiences.
- Performance batching in JSAR treats all HTML elements as 3D textured quads, enabling efficient GPU draw calls.
- Developer experience includes familiar debugging tools like Chrome DevTools Protocol, and extensibility allows embedding into 3D engines like Unity.
- Architectural differences between classic and spatial browsers include 3D world coordinates vs. 2D viewports, true 3D hit testing, and native spatial input support.
- Use cases span traditional web developers, WebXR developers, and desktop innovation, enabling spatial multitasking and immersive data visualization.
- JSAR represents a paradigm shift, making spatial computing accessible while maintaining web standards and cross-platform compatibility.
