Daniel wants to replace a 200-photo album with a digital clone of his apartment, using Polycam on a phone with no LiDAR. That constraint changes everything: without a depth sensor, the software has to infer depth from parallax across overlapping images. This episode walks through the real decisions — video versus automatic capture mode, photogrammetry versus Gaussian splatting, why object masking hurts full-room scans, and how to solve the vertical parallax problem that leaves ceilings and floors unreliable. There's also the matter of the bright ruler on the floor, which turns out to be a…
