Laser Crystal Processing
2D, 3D laser inner engraving machine can engraving 3d picture in the crystal very quickly. Take a 3D picture with 3D camera. Process it in computer to form 3D portrait, which is compatible with laser engraving machine.

Burning Crystal to Draw Points
The points are tiny (.1mm) fractures created by a focused laser beam from 3d laser engraving machine. The conical beam, with a focal length of about 3", shines into the crystal (glass) without damaging it except at the focal point. At that one point, concentrated energy heats the crystal (glass) to the cracking point, causing a microfracture.
To draw more points, the laser is pulsed on and off. To make the beam move between points, it's reflected from a mirror that is repositioned between pulses. The mirror is moved by computer-controlled motors, so many points can be drawn with great speed and accuracy. A typical design might use several hundred thousand points, or half a million isn't unusual in a large block, each placed with .001" accuracy.
Point-cloud image consists of abundant small points which are created by the special point-cloud converting software from a common two dimension or three dimension image. These points shall be engraved by laser machine according to the array order one by one. Each point will be burnt inside the transparent material, all the burnt points form the engraved image inside the crystal cube.
Image or Portrait Design
All designs are made entirely of points because the process offers no way to draw continuous lines or surfaces. However, with small enough points it's possible to arrange them into convincing curves, surfaces and volumes.
