From scan data provided (left) a Catmull-Clark control mesh (2nd) is defined, which leads to a limit surface (3rd) which approximates closely the input scan data. The error between the Catmull-Clark limit surface and teh scan data is shown in the last Figure.

This project will investigate ways in which we can produce a good internal representation from captured data that can be used for further manipulation of the model. A lot of research has been done on 3D capture and we are able to produce clean 3D meshes from scanned data with high accuracy. We will therefore start by looking at ways to produce a good representation from post-processed scan data.
