This is mainly experiment to convert 2D artwork into 3D object. Having not professional laser engraver in hand I had limited possibilities to complete this project. Keeping in mind that laser engraver works only with 2 bits images (i.e. black and white) where black color works as engraving area and white is non engraving I had really limited options. The only possible way was to use laser engraver software driver option of rasterizing grayscale image either using halftone method or difusion dither. Since I needed random rasterization method halftone pattern would not work for me so difusion dither method was the only option. To make 2D image look 3D I use very well known Depth Map method. I draw a vector image of Spasskaya tower and recolored it into grayscale. The more recessed surface I needed the more darker it was colored.
