Methods and Systems for Generating Continuous Surfaces from Polygonal Data

摘要

Methods and systems for generating surface data from polygonal data are disclosed. The methods and systems receive polygonal data which describe discrete points on an object. The methods and systems analyze and use the data to calculate and define a continuous BREP object which accurately represents the original polygonal object. In some embodiments, the generated BREP is G2 continuous at substantially all points.

1. A method of producing BREP data from electronic polygonal data, the method comprising:
accessing the polygonal data with a computer, the polygonal data defining a mesh of polygonal data points; selecting a plurality of the data points; modifying each of the selected data points by changing the positions of the selected data points to improve continuity of a plurality of regions of the polygonal data, wherein each region includes one of the selected data points; generating a plurality of continuous curves based on the modified data points, wherein one or more of the continuous curves terminates on at least one of the modified data points; based at least in part on the continuous curves, generating a plurality of surface boundaries defining one or more continuous surfaces; generating the BREP data based at least in part on the continuous surfaces; and storing the BREP data in a computer readable data storage.
