Show HN: I rebuilt my old canvas 3D library as a small WebGL 2 library – phoria2

Phoria2 is a JavaScript library for building 3D visuals on the web, including charts, dashboards and product viewers, using a WebGL 2 renderer. It has no runtime dependencies, ships as plain ES modules, and only redraws views when something changes. Every option is validated so a mistake returns an error describing the fix, aimed at both developers and coding agents. It's MIT licensed, installable via 'npm install phoria2', and includes a React example. Demos cover PBR materials, instancing, glTF models, particles, shadows, and integrations with WebAssembly libraries like Rapier for physics and Manifold for solid modeling.
