View-dependent relief surfaces

Abstract

Reliefs describe objects or scenes by sculpted surfaces. These are usually designed by compressing the depth information of target 3D shapes. Recently, several techniques are proposed to create new types of reliefs that describe images by diffuse reflection under directional lighting [1], self occlusion [2], specular reflection [3], or refraction [4]. For example, Alexa et al. proposed relief surfaces with two desired images switched by changing lighting directions [1].
