As the Cadillac design team members explain, one of the main benefits of the 3D scanning process is the creation of an archive of the hand sculpted concepts, that can be used by digital modelers as a reference for the various design iterations.
The 3D scanning technology bridges the gap between traditional hand-sculpting teams who work in clay and digital modeling design teams who work with CAD/CAS software, contributing to save time in the production of the final milled model.
Below we report the video along the full official document. Also check our previous coverage of the Elmiraj Concept.
From the official Press Release:
3-D scanning uses projected light patterns and an advanced camera to capture three-dimensional shapes and translate them into math data that can be manipulated in digital modeling programs. Developers of Elmiraj, a modern update of a classic two-door grand coupe, extensively used the digital mapping technology.
