Optical scanning is performed by structural illumination of the surface, subsequently captured by an optical scanner.
The scanner generates “clouds” from hundreds of thousands of individual points in space, which must then be converted into complex three-dimensional surfaces with well-defined, massively polygonal meshes.
This process is called triangulation, which we perform extremely efficiently and accurately. To get an idea of the complexity of this task, just imagine that you need to reconstruct the surface of the Grand Canyon within a few meters, working from five-figure sets of individual points.
After reconstruction, we automatically eliminate noise and errors that the scanner inevitably generates, we remove unnecessary vertices, simplify and refine the resulting 3D model.
