Branch, J. W., Prieto, F. and Boulanger, P. (2007). Automatic extraction of quadrilateral patches from triangulated surfaces using Morse theory. 16th International Meshing Roundtable, 411-431, Seattle, Washington, USA.
A method for decompose the triangulated surface into quadrilateral patches using Morse theory and Spectral mesh analysis is proposed. The quadrilateral regions extracted are then regularized by means of geodesic curves and fitted using a B-splines creating a new grid on which NURBS surfaces can be fitted.
