What it is
Polynode = polyfill + node. It backfills HTML5 platform APIs that Lens Studio doesn’t ship — DOM, 2D Canvas, SVG, EventEmitter — so existing JS/TS libraries can be ported to Snap Spectacles without rewriting from scratch.
Modules
SpaceCanvas is a drop-in replacement for HTML5 canvas. It uses the WebView and a few patterns the Snap team shared on the Reddit forums. There are 4 samples: a general gallery, something resembling Snakes, a bad shooter, and Conway’s Game of Life. SpaceCanvas runs hot — WebViews overheat the Spectacles thermals — so a tuning pass is scheduled.
SpaceSVG is the gem. It converts SVG strings into meshes that look nice and run efficiently. It isn’t fully spec-compliant but it’s solid enough to render 2D shapes, illustrations, and animations. SpaceSVG is what made the LaTex port (Matematex) viable.
SpaceDOM is a minimal DOM shim — alpha — useful when you’re trying to get a library to even compile in Lens Studio. Bug reports welcome.
EventEmitter is a hand port of node’s pattern, used across IoTone’s lenses for clean inter-script messaging.
In production
Used by Spectacles-Matematex for math notation in AR, the Moire Lens Lab art-book project, and several IoTone Japan client builds.
Roadmap
SpaceCanvas thermals tuning · SpaceSVG spec-compliance pass · SpaceDOM beta with worked examples · LaTex 1.0 release on Matematex.
