Let's have a look at the process of generating CGI pictures (Computer Generated Imagery) of a watch.
Once the watch is 3D modeled (meaning that the design and construction have been done), the file is imported in a dedicated software to add lights, shadows, materials, textures and colors.
The main steps are the following ones:
1) import 3D file and bugs fixing
2) polygons (there are different methods to map the volumes. Here we use polygons)
3) lights
4) texturing
5) rendering lights + textures
6) retouching and final result
It needs quite a lot of time, patience, and tests to play with hundreds of settings, then retouch the picture in another software to reach the realism or style expected.
