Interesting paper for someone fiddling with implicit surfaces, but it's gonna take a little while to digest it. Also there's no examples of resulting UV maps used in this (while on-model painting is simplified, afaik classically artists still preferred to get clearly delineated maps to modify in regular painting software even if stuff like Substance painter seems to have shifted that).<p>Implicit surface modelling tools are still evolving quickly, and one point that seems overlooked is how this would tie with authoring tools (since this is about a fairly raw numeric algorithm solution).<p>Post-modelling it should hold up, but would the maps retain similarity (or enable transferability) if the implicit model structure changes?<p>Imagine 2 disjoint spheres in space, the user drags them together, would this algorithm want to merge the UV mapping of them if they are smoothly joined? (no sharp creases).
