Amazing, Daniel! Thanks for making the work of this research group available to us.
I have done some splitting using angle thresholds and minimal face counts in Ivy and the results are promosing. I subsequently flattened using a Zombie Solver by using an OnPlane constraint and Hinge with rest angle at 0.
The paper has some interesting examples using meshes from topology optimisations, which is a great idea. It could be nice also to work with RemeshByColour outputs to see what details could be achieved. With the horse it could be good to have higher mesh resolutions in the tight parts, which I omitted.
