Abstract:
A method for production of 3D laser-induced head image inside transparent material by using 2D portraits, comprising the steps of:creating 3D head model so that its front view corresponds to the 2D face portrait and its side view corresponds to the 2D profile portrait; creating the first aggregate of points, which gives the information about spatial configuration of 3D head image; all points of the first point arrangement are located on the surface of 3D head model, so that laser-induced breakdowns can be produced at the transparent material points, corresponding to the points of the first aggregate, without internal split; transforming the first point aggregate into the second point arrangement, so that the second point arrangement keeps information about spatial configuration of 3D head image and contains complete information about 2D portraits, which are used for creation of 3D head model; all points of the second point arrangement are located in the area of the 3D head model so that laser-induced breakdowns being produced at the transparent material points, corresponding to the points of the second arrangement, do not generate internal split of the transparent material; generating laser-induced breakdowns at the transparent material points corresponding to the points of the second arrangement.
