Triangulation in "Reverse Engineering" Applications

Machining of free-form surfaces requires an accurate and efficient tool trajectory planning. In order to apply any of different planning strategies, a well-defined surface description function must be provided. This usually makes the first step of the complex manufacturing task and represents the main goal of the reverse engineering approach. In this paper we are concerned with the problem of constructing triangulation which satisfactorily approximates an original model surface and provides a convenient support for the tool-path planning CAD applications. According to that, the global approximating surface construction algorithm is presented. An example of the hemisphere approximation illustrates algorithm performance and supports the discussion upon the algorithm optimality criteria.
