Figure 3
The illustration contains three panels labeled “(a)”, “(b)”, and “(c)”, each displaying overlapping point clouds in blue and yellow. In panel (a), a circular top view shows a dense blue disk of points surrounded by a thick yellow ring of points; the two colors are clearly separated, with blue in the center and yellow forming the outer band. In panel (b), a filled circular view shows the same two datasets but more intermingled: blue and yellow points cover the disk with broad horizontal and diagonal zones where one color dominates and regions where the colors mix, suggesting surface differences between scans or models. In panel (c), a narrow vertical shape is shown in side view, resembling an irregular, slightly curved column; blue and yellow points lie on opposite sides of the shape along most of its height, with some portions where one color wraps around or overlaps the other.Comparison of point cloud data sets
