Truncated signed distance function (TSDF).
(a) and the TSDF that was interpolated (b). Every voxel is represented as a dot in the grid, while the black line represents the surface. Positive distances are indicated by the colour blue to green; negative distances are indicated by the colour green to red. [103].
