Profile

Overview: Wen Eng’s main research interest is curve and surface reconstruction. It is one of the significant applications of scattered data interpolation and approximation. In practice, it is very much related to the subject of computational geometry and object modelling where curve, surface, solid or object representation is to be sought from a given finite set of data. The obtained mathematical representation is often studied and the reconstructed object is placed in computer graphics environment for viewing, printing, or further manipulation.
