(A, B). Three measurement areas defined in each skull through bilaterally selected mesh surfaces at the forehead (blue), the zygomatic process (green), and the maxillary process (red) for reproducibility and trueness assessment, respectively. Each circular area shown in the images consists of 1000 triangles. (C). Reference area (light blue) used for all surface-based superimpositions performed in the study.
