Reduced Depth and Visual Hulls of Complex 3D Scenes

“…They used a volumetric approach to construct a depth hull from reference range images. More recently, the depth hull was used for novel view synthesis in a free-viewpoint video setup [BGM06].…”

“…Any of the existing DH rendering algorithms [BGM06] can be used, as long as they satisfy the following condition: At the rasterization step 3D coordinates of the fragments are available. Steps 4-10 of Algorithm 1 ensure that the rendered fragment lies between the first and the second depth layer of some reference view.…”
