Geodesics and geodesic distance maps. a Geodesic path (black line) from the source (red circle) to the end (green circle), with no curvature weights on edges (red line is the Euclidean shortest path). b Geodesic path from source to end with curvature weights on the edges. c Euclidean distance map from source to all the points. d Non-weighted geodesic map from source to all the points. e Weighted geodesic map from source to all the points. The point cloud color follows the magnitude of distance proportional to wavelengths in visible spectrum (violet (minimum), red (maximum))
