ArXi:2602.05321v2 Announce Type: replace We present Wid3R, a feed-forward neural network for multi-view visual geometry reconstruction that s wide field-of-view camera models. Unlike existing methods that assume rectified or pinhole inputs, Wid3R directly models wide-angle imagery without explicit calibration or undistortion. Our approach leverages a ray-based representation with spherical harmonics and
