Direct
digital design and manufacturing from massive scan data (supported by NSF)
The goal is to develop computational
tools enabling a new way of developing products, direct design and
manufacturing from 3D sensing of pre-existing objects, one that
can bypass the painstaking CAD model reconstruction involved in current
product development process.
If
successful, this research would change the way a large number of 3D parts
are developed, enable custom product development at mass production
efficiency by circumventing laborious and error-prone CAD model
reconstruction and lead to quantum-leap progress in bringing physical
objects into digital space for direct engineering processing.
