From GoPro footage to 3D scenes: a two-week agent skill for full-home reconstruction
doodlestein · x · 2026-09-26
- doodlestein spent two weeks building an agent skill that turns drone footage into a 3D exterior scene of your house, plus a far more complex companion skill that reconstructs interiors from footage shot with Meta Gen2 glasses and an iPhone 17 Pro Max.
- The interior skill is really a hybrid system with lots of custom code, not just a prompt.
- The core challenge was aligning interior geometry with the exterior. He prompted the agent to devise a "constraint propagation" dynamic-programming approach — modeling features in isolation then fitting the jigsaw together using exterior-visible cues like AC units and skylights — and the agent implemented the improvement itself.
- A showcase of the paradigm: describe domain reasoning to the agent and let it iterate the skill.
