Abstract: The present application relates to a method of and a non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to perform laser engraving a three-dimensional pattern into a surface of a workpiece, the method comprising: positioning a laser-engraving head to engrave a first engraving region of the workpiece; and applying a first plurality of laser pulses to a set of first predetermined locations within the first engraving region, wherein the first set of predetermined locations within the first engraving region is based on a probability distribution function that corresponds to a portion of the three-dimensional pattern that is associated with the first engraving region. The present application relates also to a method of determining locations (403) for laser pulses of a laser engraving process to engrave a three- dimensional pattern into a surface of a workpiece.
