Engineers can now reverse-engineer 3D models
A system that uses a technique called constructive solid geometry (CSG) is allowing MIT researchers to deconstruct objects and turn them into 3D models, thereby allowing them to reverse-engineer complex things.
The system appeared in a paper entitled "InverseCSG: Automatic Conversion of 3D Models to CSG Trees" by Tao Du, Jeevana Priya Inala, Yewen Pu, Andrew Spielberg, Adriana Schulz, Daniela Rus, Armando Solar-Lezama, and Wojciech Matusik.
"At a high level, the problem is reverse engineering a triangle mesh into a simple tree. Ideally, if you want to customize an object, it would be best to have access to the original shapes — what their dimensions are and how they're combined. But once you combine everything into a triangle mesh, you have nothing but a list of triangles to work with, and that information is lost," said Tao Du to 3DPrintingIndustry. "Once we recover the metadata, it's easier for other people to modify designs."
