Attached shadow coding: Estimating surface normals from shadows under unknown reflectance and lighting conditions
We present a novel technique, termed attached shadow coding, for estimating surface normals from shadows when the reflectance and lighting conditions are unknown. Our key idea is ...

3D Reconstruction of Metallic Surfaces by Photopolarimetric Analysis
In this paper we present a novel image-based 3D surface reconstruction technique that incorporates both reflectance and polarisation features into a variational framework. Our tec...

Applications of irradiance tensors to the simulation of non-Lambertian phenomena
We present new techniques for computing illumination from non-diffuse luminaires and scattering from non-diffuse surfaces. The methods are based on new closed-form expressions d...

Re-tiling polygonal surfaces
This paper presents an automatic method of creating surface models at several levels of detail from an original polygonal description of a given object. Representing models at var...
