Tri2NURBS Input: triangular mesh Output: a conforming quad layout, followed by NURBS interpolation. Frist step: compute eigen functions eigens(input, 'EigenFunctions', num) Second step: Morse Smale Quadrangulation morseSmaleQuadrangulation("EigenFunctions.vtu", "./Quadrangulation", num, start) Third step: singularities and separatrices pt_list, idx_patches = conformal_patch_gen(f'./Quadrangulation/EigenFunction{id}.obj') Fourth step: NURBS multi-patch surface approximation degree_us,degree_vs,kv_us,kv_vs,ctrlpts_size_us,ctrlpts_size_vs,ctrlpts,weights=approximate_mp_nurbs_surf(pt_list, idx_patches,max_deg,ctrlpts_size)
