Could you build this?
Partial The API surface (scene graph, labels, picking, glTF loading) is codeable with AI help, but a robust WebGL 2 renderer with PBR, shadows, and performance tuning needs real graphics-programming expertise that vibe coding alone won't reliably supply.
What it would actually take: Build on the WebGL 2 API with plain ES modules and no dependencies, structuring a scene graph, a render loop that redraws only on change, and instanced draw calls. The hard parts are the PBR lighting and shadow pipeline, GPU picking, and a correct glTF 2.0 loader, which need someone who understands shader math and GPU performance. Testing across browsers and devices is also needed.
