This glossary explains terminology related to volumetric engraving inside crystal and transparent materials. The definitions focus on how images are formed beneath the surface rather than on surface cutting or marking.
Subsurface engraving uses controlled internal points placed in three-dimensional space. Because the image exists inside the material, specialized preparation methods and data types are required.
The following terms describe the processes, data formats, and materials involved in this method of engraving.
A method of forming an image using many individual internal points positioned in three-dimensional space.
A process where a laser focuses energy beneath a transparent surface to create internal marks.
A three-dimensional image suspended within a material rather than on its surface.
Two different representations of depth information used for relief carving and volumetric imaging.
A transparent optical material designed to accept internal laser points without visible cracking.
Detailed explanations are available on each term’s page.
Software such as Cockpit3D is used to prepare data for this type of engraving workflow.
