Acquiring 3D models from rotation and highlights

This paper proposes an approach to acquire 3D models of objects with specular reflectance for graphics use. Highlight and rotation informations are employed in the model recovery. The authors control object rotation and extract motion of a highlight stripe, from which the object shape can be qualitatively inferred and quantitatively reconstructed by solving a first-order linear differential equation. The authors have experimented on simulated and real objects to obtain their models
