Ever wondered what's actually inside an E57 file?
If you work with laser scanning or reality capture, you export E57s all the time — but the format itself stays a bit of a black box. We wrote a explainer that opens it up, no heavy math:
• How one open file packs millions of measured 3D points, plus their colour and laser intensity
• Its XML-tree-and-binary layout — think of E57 as the "PDF of point clouds"
• The three ways a photo can live inside a scan (spherical, pinhole, visual-reference) — and why the very same file can look different from one program to the next
• How a full 360° panorama, fake sky points and all, gets woven right into the point grid
