Visualising an Egyptian Artefact in 3D: Comparing RTI with Laser Scanning
3D digital representations of an ancient Egyptian artefact were compared for their rendering of surface detail. Normals were generated by three methods: (1) point clouds from the Arius 3D colour scanner; (2) reflectance transform imaging (RTI); (3) photometric stereo. The latter two were constructe…
