Aims

This project is investigating how to produce geometric models from 3D point data captured from the surface of an object. Such objects may range from simple to highly intricate ones including many complex curved surfaces and blends between those surfaces. It is intended to produce complete and detailed boundary representation geometric models, which contain explicit bounding surface equations and topological relationships between the adjacent vertices, edges and faces.

The software will be written to operate in conjunction with the existing ACIS solid modelling kernel and the FFS-GT geometric modeller. The standard output format of the models produced in this project will ensure that these can be further used not only within these CAD systems but in other commercial modellers as well.

Tasks

To achieve this objective the following tasks will have to be satisfied:
