Fig. 8

Comparison of STL models between S3D (a) and MIT (b), where the shape error between the two STL models was the minimum value. Visualization of the shape error (signed differences) after superimposition is shown on the right (c). Almost all of the STL model was green. The mean error between the two STL models was 0.00 mm (maximum + 0.16 mm, minimum − 0.17 mm)
