Camera calibration from a single photo, using vanishing points. Trace parallel edges in the photo; Fuga solves the focal length, rotation and position of the camera and exports it for Blender, Maya, USD (Houdini, Cinema 4D, Unreal…) or JSON.

Fuga was designed and directed by Gelain, a motion designer and 3D generalist, to find the exact camera behind a photo (its lens, angle and position) and bring it into 3D software, so the scene lines up with the picture without trial and error. It was built with the help of AI. Every result is checked by automated tests against cameras with known values, and the source is public for anyone to review. Report a problem.
Fuga collects no data. The only network request is an optional check for new versions on GitHub. See PRIVACY.md.
