Interactive Editing of Voxel-Based Signed Distance Fields

Signed distance functions computed in discrete form from given RGB-D data as regular voxel grids can represent manifold shapes the zero crossing of a trivariate function; corresponding meshes be derived by Marching Cubes algorithm. However, 3D models automatically reconstructed this way often contain irrelevant objects or artifacts, such holes noise, due to erroneous scan and error-prone reconstruction processes. This paper presents an approach for interactive editing signed functions, grids, that enables manual refinement enhancement geometry. To end, we combine concepts known constructive solid geometry, where complex are created simple base shapes, with voxel-based representation geometry real-world scans. Our implemented entirely on GPU enable real-time interaction. Further, present how implement high-level operators, copy, move, unification.
