@@@@BACKGROUND:Reverse engineering technology has been widely used in surgery, and how to produce the model that meet the rapid prototyping processing rapidly and effectively has attracted more and more attention. @@@@OBJECTIVE:To compare the classical surfacing and rapid surfacing for complex surface reconstruction based on the summary of the commonly used surface reconstruction modeling technique. @@@@METHODS:VIVID9i non-contact three-dimensional digital scanner produced by Konica, Japan was used to perform the three-dimensional coordinate measuring on faces of 30 col ege students. The classical surfacing and rapid surfacing approaches were used to surfacing reconstruct the facial point cloud data, and to perform error analysis and smoothness evaluation. @@@@RESULTS AND CONCLUSION:The results show that the maximum distance of surfaces and point clouds reconstructed with the classical surfacing and rapid surfacing approaches were 2.99 mm and 0.69 mm. The surface made by classical surfacing approach was smoother than that made by rapid surfacing approach. There is a conclusion that rapid surfacing approach is more efficient method for complex surface reconstruction, and provides a reference for the three-dimensional reconstruction of complex surfaces.
