NebulaViewer: 3M-triangle GLTF on Apple (Swift + AFM)

A Swift/AFM tool that loads a massive GLTF model and tags viewpoints with AI.

Wed Jan 14 2026 • Swift, AFM, GLTF, Apple

Summary

This work focuses on pushing Apple’s rendering stack to handle multi-million-triangle GLTF scenes interactively, then layering a viewpoint tagging workflow.

Notes

  • Add benchmarks (load time, FPS, memory).
  • State constraints (device, OS version, triangle count).
  • List what you learned or what you’d do next.
