Can all the laser sub-surface engraving machine engrave 3d portrait or images?
Yes. Theoretically, all the sub-surface engraving machines can engrave all the images including the 3d portrait inside some transparent material. Laser sub-surface engraving machine is only used for output laser and locating the special position of laser point or the transparent material. It does not deal with any image. The image is pre-processed by the point-cloud converting software. The machine only accepts the input point-cloud image and engraves the points inside the transparent material by the engraving control software (This software only control the movement of laser or the transparent material). A 3d portrait output by a 3d camera has to be converted into a 3d point-cloud image first. 3d portrait point-cloud image is one of point-cloud images. So, 3d portrait laser subs-urface engraving machine is only a conception, in fact, it can engrave all the point-cloud images inside the transparent material. That is to say, all the sub-surface engraving machines can engrave all the poi
