WebBase class of the Truncated Signed Distance Function (TSDF) volume This volume is usually used to integrate surface data (e.g., a series of RGB-D images) into a Mesh or PointCloud. The basic technique is presented in the following paper: A volumetric method for building complex models from range images Curless and M. Levoy In SIGGRAPH, 1996 WebAn improved CSC algorithm on GPUs. An extended Characteristics/Scan Conversion (CSC) algorithm [1] is used to generate a narrow band SDF from triangulated surfaces (figure 1). 3D extrusions are generated from the features of the input shape. The computational mesh vertices inside these volumes are assigned the minimum distance to the features.
