DETROIT – Structured-light 3-D scanning, an advanced measuring technology often used for fine art restoration and reproduction, helped create a “work of art” in the Cadillac Elmiraj concept car – appearing at the Los Angeles International Auto Show through Dec. 1.
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.
“With the Elmiraj, we were able to use 3-D scanning as the bridge between traditional hand-sculpting teams who work in clay and digital modeling design teams who work in math,” said Frank Saucedo, director of General Motors’ North Hollywood Advanced Design Studio. “Our ability to scan the clay model with speed and precision and go from the digital tools to the hands of a craftsman and vice versa was extremely valuable.”
