Abstract
Dot representation is the only format accepted in a special 3D printing application called laser stippling, which outputs the shape and texture tone of a 3D model inside a lead glass by using laser beam. To fully utilize existing abundant and exquisite 3D triangular-meshed models, this study proposes a two-phase technique, i.e., a sampling phase followed by a halftoning phase, to convert models in triangular-meshed format to dot representation. The sampling phase generates a set of dense sample points that cover the entire surface of the model, and the halftoning phase removes some of the sample points to reflect the tone of the model’s texture. The actual stippled results demonstrated the technique could deliver products in good quality.
