3D model of a punch mark (0.8 mm in diameter) from the lotus of a Buddha Vairocana (see fig. 285). The model was generated by a digital microscope using automated focus stacking. Note the asymmetry in the punch mark resulting from a defect in the face of the punching tool. Buddha Vairocana, Indonesia, first half of the 10th century, H. 12 cm (Musée national des arts asiatiques – Guimet, Paris, inv. MA 3475).
