Fig. 10From: Alpha shapes: determining 3D shape complexity across morphologically diverse structures‘Coarsest refinement’ point clouds. Ventral surfaces of mustelid, ursid and canid bacula (left to right). Points are coloured according to the coarsest alpha-shape to which they contribute. The urethral groove of the mustelid baculum is identified as being particularly ‘complex’ according to the alpha-shapes methodologyBack to article page
