The schematic map of the rotating sphere model. Part A indicates the coordinate system (X, Y and Z) in Vaa3D platform, the two red dots (S and T) imply the starting and terminal node respectively. Part B means the new coordinate system (X’, Y’ and Z’). Part C illustrates the rotating procedure from the starting voxel (marked with red (a)) to the terminal voxel (marked with red (d)). Red (b) and red (c) are the schematic sphere center which are selected from the rotating procedures
