What is 3d Scanning?

3d scanning, the process that produces a 3d scan. This process gets generalized into a single word. But, behind that one word is a big list of stages one must go through in order to generate a 3d scan.

As there are a few 3d scanning techniques on the market right now, the one I'd like to concentrate on in particular is the Photogrammetry technique.

So, what are the stages? Well, here we have the list of main procedures of interest. Some stages will be similar to other 3d scanning techniques while others are strictly native to the manipulation of data acquired with the use of a Photogrammetry System, such as the one we have at Scanlab.

Without further ado, The List:
00. Photogrammetry Hardware
01. Capture of RAW Photos
02. Correction of RAW Profiles
03. Conversion to TIFF or another compatible file format
04. Masking of Background
05. Alignment, Scaling and Reconstruction of RAW Geometry in Photoscan / Capturing Reality
06. Export of Geometrical Elements
07. Refinement of Geometry in Zbrush
08. Retopology of Geometry in Maya
09. Layout of Element's UV / UDIM
10. Reprojection of Albedo Texture
11. Refinement of Albedo Texture
12. Customization of Output for Platforms
13. Generation of Textures: Normal, Displacement, SubSurface Scattering
14. Export to OBJ / FBX / GLTF
15. Addition of Generic Accessories

When all is said and done, the resulting product is called a “3d Scan”. Yet, as mentioned before, each stage involves its own processes and with those processes comes a whole array of skills required to produce a quality 3d scan.
