Generation of Trimmed Surfaces With G1-Continuity For Reverse Engineering

Abstract

In the field of automotive style design, reverse eingineering technology that automatically generates CAD (Computer Aided Design) data from measurement data is gathering attention. In order to apply it for practical use, it is necessary to fit a suitable trimmed surface to the triangle mesh data given as measurement data. Especially in the design , it is important functionally and design-wise that the boundaries of the fitted trimmed surface are smoothly connected.

In this study, we propose a trimmed surface fitting method that G¹-continuity for the triangle mesh given as measurement data, and describe details and results of own method.
