Astra turns photogrammetry scan of old home into editable 3D scene, hinting inverse graphics has crossed the chasm

The author fed 400 photos taken in 2019 through RealityScan to build a photogrammetry mesh, then imported it into Blender and used Astra to convert it into a fully editable, cleaned-up 3D scene — reusing scanned textures and generating procedural shaders for the rest.
Results are impressive but imperfect: some artifacts (bird statue legs, furniture contours) were inherited from the RealityScan reference mesh, showing humans still hold the edge in "spatial autocomplete."
His takeaway: multimodal LLMs may have crossed the chasm on inverse graphics, with big implications for VFX, AR/VR and robotics. Next step: letting Astra drive CUA to interactively reference source imagery and refine the scene in Blender.
