Research Interests



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.
