"Exact Constraint Satisfaction for Truly Seamless Parametrization"
Manish Mandad, Marcel Campen
Computer Graphics Forum 38 (2), 2019.


The folders "myles_truly_seamless" and "bommes_truly_seamless" contain the 113 and 92 exact output parametrizations (stored as texture coordinates in .obj format) generated by the method described in the above paper. The corresponding inexact input parametrizations were taken from the dataset published by Myles et al. as supplement to their 2014 paper "Robust Field-aligned Global Parametrization".

Note that the stored texture coordinates have double precision (17 digits in ASCII-obj); be aware that there seem to be some .obj reader implementations out there that do not read these with full precision.

The file "seamless-test.cpp" contains a small self-contained test program. It can be called with an .obj file as argument and checks the exactness of seamless transitions in the parametrization represented in the texture coordinates. Calling it with the files from the folders "myles_truly_seamless" and "bommes_truly_seamless" verifies their correctness, while calling it with the original files from the above mentioned dataset reveals many minuscule inaccuracies in every single case.
